The face of a tent is shaped like a triangle with an area of Fifteen 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 4 feet. How wide is the base of the tent?

Respuesta :

Step one: Set up equation
    A=1/2bh
Step two: plug all known numbers in
  15=1/2b(4)
Step three: Simplify all sides of equation
   15=2b
Step four: Divide each side by 2
    15/2=7.5
7.5=b

The height is 7.5ft.
