The face of a tent is shaped like a triangle with an area of Fifteen point one two five feet squared. The area of the triangle is represented by the formula A equals one half b times h. The height of the tent is 5.5 feet. How wide is the base of the tent?

5.5 feet

6.0 feet

6.5 feet

7.0 feet

Respuesta :

The answer is 5.5 feet.

15.125= 1/2 * b* h

15.125= 1/2 * b* (5.5)

2(15.125)= 2 (1/2 * b *(5.5))

30.25= b * 11

30.25/11= b * 11/11

2.75 = b

You have to check it so when you plug the solved variable back in

15.125= 1/2 * (2.75) * (5.5)

15.125=  7.5625

So because the original b variable does not equal to the area of the triangle, you multiply the b variable by two to get 5.5 and when you plug that in, you get 15.125.
