Answer 2

70.8 inches

Explanation:

The area of the side is 21 (3x7) and the other side is also 21, the area of the triangle part is 3.9 because to find the area of a triangle you have to do it normally and then divide it by 2. The other triangle would also be 3.9 the base of the triangle is 21 (3x7). 21+21+3.9+3.9+21=70.8
