What is the area of this composite figure?
Mkey [24]

We have two congruent trapezoids.

The formula of an area of a trapezoid:

A=\dfrac{base_1+base_2}{2}\cdot\ height

We have:

base_1=210\ mm\\\\base_2=150\ mm\\\\height=55\ mm

Substitute:

A=\dfrac{210+150}{2}\cdot55=\dfrac{360}{2}\cdot55=180\cdot55=9,900\ mm^2

Answer:

2A=2\cdot9,900\ mm^2=19,800\ mm^2
