Question

What is the area of the shaded part of the triangle ?

Answer 1

Area of the triangle is 1/2 ( b * h) so
1/2 (12 * 14)
12 *14 = 168 then 168 * 1/2 = 84 so the area of the full triangle is 84cm but to get just the shaded area subtract the full triangle area and the squares area.

area of a square is ( b * h ) so 3.5 * 3.5 = 12.25

so the triangles area is 84 cm - 12.25 = 71.75

answer is D 71.75 cm

Answer 2

I got D for this one................
