Question

1.st Find the area of the shaded portions
2nd write the area of the shaded portion in mm2​

Answer 1

Step-by-step explanation:

In triangle STU

(TU) 2=( TS)2+(SU)2 ( BY PYTHAGORAS THEOREM)

(10)2+(10)2

100+100=200

TU=√200

TU=√2×5×2×2×5

TU=10√2 cm

Again in triangle UQR

(UQ) 2= (10)2+(20)2

UQ=√100+400

√ 500

√ 5×10×10

UQ=10√5=TQ

Therefore,the triangle is isosceles

Now find the area of triangle
