I think the above question needs a correction and `O` is the point of intersection of `TU` and `QS`. Assuming the above condition, The required area OTS is a triangle having two sides are equal and angle `STO` is right angle. So that the triangle OTS is a regular right angled triangle. Here PQ = PS...

Here PQ=PS = 8cm=> ST=4cm => area OTS = 1/2 * 4 * 4 sqcms = 8 sqcms read less

PQRS IS SQUARE AND T AND U are mid pts of PS &QR, TU//PS AND TU=PS(DINCRVPQRS IS A SQUARE), JOIN QS WHICH INTERSECTS TU AT O, IN ∆PQS ST/TP=1(T IS MID PT OF SP) AND TO//PQ, THEREFORE O IS THE MID POINT OF SQ, by theorem, TO//PQ AND TO=1/2 OF PQ =4CM, AR. OF ∆OTS= 1/2*TS*OT=1/2*4*4=8 SQ.cm

How many triangles can be drawn having its angles as 45°, 64° and 72°? Give reason for your answer.
Zero triangles.. we cant draw triangle with these angles. but the given angles are 45,64.72. if we add those we get 45+64+72=181. so we cannot draw triangle.

Solve : 141x + 103y = 217; 103x + 141y = 27
First add both equations, we'll get 244x+244y=244, Now, Divide this equation by 244, it gives x+y=1.....(a) Again, subtract equation 2 from 1, it gives 38x-38y=190, Now, divide this equation by 38,comes x-y=5.....(b) Now...

The sides of a triangular plot are in the ratio of 6 : 7 : 8 and its perimeter is 420 m. Find its area.
Let,the sides are 6x, 7x, 8x. perimeter =420m 6x+7x+8x=420 21x=420 x=20. So the sides are 120,140,160 respectively. now area =root (s(s-a)(s-b)(s-c)) =root(210*90*70*50) =8133m^2

many of you have a problem a to square, cube a no..
There is a trick to do it Just remember (a+b)² = a² + 2ab + b² Now remove + sign (a/b)² = a²/2ab/b² You can find square easily Ex will be in a next post Bye
