Due today!
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

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.
