Pls help. Thks!
1st big triangle = trapezium + overlap
2nd big triangle = shaded area + overlap
comparing above, deduce
trapezium = shaded area = 5×5 + 1/2 x 3 x 5
= 32.5 sq cm
Thanks so much, SAHMOM!
The figure shows two identical right-angled triangles overlapping each other. Find the area of the shaded part.area of the shaded part ——- (8 x 5) – (1/2) x 5 x 3 = 32.5
Ans : 32.5 sq cm.
