What is the area of the figure? a. 90 mm2 b. 110 mm2 c. 130 mm2 d. 180 mm

I see two shapes in the given figure. A rectangle and a triangle.

We need to get the area of the rectangle and triangle. We then deduct the area of the triangle from the area of the rectangle to get the area of the shaded portion.

Area of the rectangle = length * width 
A = 11 mm * 10 mm 
A = 110 mm²

Area of the triangle = (hb)/2
A = [(11mm-7mm)(10mm)] ÷ 2
A = (4mm*10mm) / 2
A = 40mm²/2
A = 20mm²

 110 mm² - 20mm² = 90 mm²  Choice A.

The answer would be d i think but i’m for sure it is not a and c
