For finding the area of the paper used, determine the area of each part separately and then find the sum of the areas to get the area of used paper.

**For region I (Triangle)**

Length of the sides of the triangle section I = a=5cm, b=1cm and c=5cm

Semi Perimeter of the triangle,

s =( a+b+c)/2

s=(5 + 5 + 1)/2= 11/2cm

Semi perimeter = 11/2 cm = 5.5cm

Using heron’s formula,

Area of section I = √s (s-a) (s-b) (s-c)

= √5.5(5.5 – 5) (5.5 – 5) (5.5 – 1) cm²

= √5.5 × 0.5 × 0.5 × 4.5 cm²

= √5.5 × 0.5 × 0.5 × 4.5 cm²

= 0.75√11 cm²= 0.75 ×3.32 cm²

= 2.49 cm² (approx)

**Section II( rectangle)**

Length of the sides of the rectangle of section II = 6.5cm and 1cm

Area of section II = l ×b= 6.5 × 1

= 6.5cm²

**Section III is an isosceles trapezium**

In ? AMD

AD = 1cm (given)

AM + NB = AB – MN = 1cm

Therefore, AM = 0.5cm

Now,AD² =AM² +MD²

MD²= 1² – 0.5²

MD²= 1- 0.25= 0.75

MD = √0.75= √75/100=√3/4cm

Now, area of trapezium = ½(sum of parallel sides)×height

=½×(AB+DC)×MD

=½×(2+1)×√3/4

= ½(3)×√(3/4)= ½×3×√3×2=(3/4)√3

= (3/4)×1.73= 1.30cm²(approx)

[√3=1.73....]

Hence, area of trapezium = 1.30cm²

**Section IV and V** are 2 congruent right angled triangles with base 6cm and height 1.5cm

Area of region IV and V = 2 (½ × 6 × 1.5)cm² = 9cm²

Total area of the paper used = Area I + Area II + Area III + (Area IV + Area V) = (2.49+ 6.5 + 1.30 + 9)

= 19.3 cm² (approx)

Heron's Formula for the area of a triangle(Hero's Formula)

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a=15m,b=11m,c=6m be the lengths of the sides of a triangle. The area is given by:

Area = √p(p−a)(p−b)(p−c)

where p is half the perimeter, or (a+b+c)/2 = (15+11+6)/2 =16m

Therefore, Area = √16(16-15)(16-11)(16-6) = √16(1)(5)(10) =20√2 = 20 × 1.414 = 28.28 m²

For finding the area of the paper used, determine the area of each part separately and then find the sum of the areas to get the area of used paper.

**For region I (Triangle)**

Length of the sides of the triangle section I = a=5cm, b=1cm and c=5cm

Semi Perimeter of the triangle,

s =( a+b+c)/2

s=(5 + 5 + 1)/2= 11/2cm

Semi perimeter = 11/2 cm = 5.5cm

Using heron’s formula,

Area of section I = √s (s-a) (s-b) (s-c)

= √5.5(5.5 – 5) (5.5 – 5) (5.5 – 1) cm²

= √5.5 × 0.5 × 0.5 × 4.5 cm²

= √5.5 × 0.5 × 0.5 × 4.5 cm²

= 0.75√11 cm²= 0.75 ×3.32 cm²

= 2.49 cm² (approx)

**Section II( rectangle)**

Length of the sides of the rectangle of section II = 6.5cm and 1cm

Area of section II = l ×b= 6.5 × 1

= 6.5cm²

**Section III is an isosceles trapezium**

In ? AMD

AD = 1cm (given)

AM + NB = AB – MN = 1cm

Therefore, AM = 0.5cm

Now,AD² =AM² +MD²

MD²= 1² – 0.5²

MD²= 1- 0.25= 0.75

MD = √0.75= √75/100=√3/4cm

Now, area of trapezium = ½(sum of parallel sides)×height

=½×(AB+DC)×MD

=½×(2+1)×√3/4

= ½(3)×√(3/4)= ½×3×√3×2=(3/4)√3

= (3/4)×1.73= 1.30cm²(approx)

[√3=1.73....]

Hence, area of trapezium = 1.30cm²

**Section IV and V** are 2 congruent right angled triangles with base 6cm and height 1.5cm

Area of region IV and V = 2 (½ × 6 × 1.5)cm² = 9cm²

Total area of the paper used = Area I + Area II + Area III + (Area IV + Area V) = (2.49+ 6.5 + 1.30 + 9)

= 19.3 cm² (approx)

A method for calculating the area of a triangle when you know the lengths of all three sides.

Let a=15m,b=11m,c=6m be the lengths of the sides of a triangle. The area is given by:

Area = √p(p−a)(p−b)(p−c)

where p is half the perimeter, or (a+b+c)/2 = (15+11+6)/2 =16m

Therefore, Area = √16(16-15)(16-11)(16-6) = √16(1)(5)(10) =20√2 = 20 × 1.414 = 28.28 m²
