Question

A figure is made up of four triangles. Each triangle has a baseof 13 inches and a height of 8.2 inches. What is the total area ofthe figure?

Answer 1

We need to find first the area of one triangle, and that area is equal to

$A=\frac{b\cdot h}{2}=\frac{13\cdot8.2}{2}=53.3$

Now the total area of the figure is 213.2 inches^2

$A_T=4\cdot A=4\cdot53.3=213.2$
