Question

What is the area of this trapezoid?
A. 14 m2
B. 18 m2
C. 21 m2
D. 35 m2

Answer 1

b

Explanation:

yes

Answer 2

B

Explanation:

If we draw another vertical line on the other side, we can split this into a rectangle and two triangles. The width of the rectangle is 5 m, so the base of the triangle on the left is 1 m, just like the triangle on the right.

The area is therefore the sum of the areas of each shape:

A = Arectangle + 2Atriangle

A = (5 m)(3 m) + 2(½ (1 m)(3 m))

A = 18 m²
