Let?ABC be required triangle AB=AC=5cm BC=8 cm Let AD be the altitude We know that perpendicular drawn from vertex bisect the base. Therefore BD=4 cm Using Pythagoras theorem we get AD= 3 cm Area of ?ABC=1/2 × base×height =1/2×8×3=12 cm2

Perpendicular on base of isoceles triangle bisect the third side. So using pythagoras we get height = 3 cm Now area of triangle= 1/2 *height *base =1/2*8*3=12 sq cm

Find the cost of polishing a circular table-top of diameter 1.6 m, if the rate of polishing is ` 15/m2. (Take (π) = 3.14)
Diameter=1.6m Radius r=1.6÷2=0.8m Rate of polishing= 15/m² Area of table=πr²=3.14×0.8×0.8=2.0096m² Now Cost=2.0096×15=₹30.14

Solve : x + y = 18; y + z = 12; z + x = 16
Let x+y=18---(1), y+z=12---(2),z+x=16---(3) Solving (2)-(3) we get y+z-z-x=12-16 y-x=-4--(4) Solving (4)+(5) we get x+y+y-x=18-4 2y=14 y=14/2=7 Substitute y value in (1) x+7=18 x=18-7=11 Substitute x value in (3) z+11=16 z=16-11=5 x=11, y=7, z=5
