The area of a rectangular gymnasium is (5x+5x) square feet. If it is 5x feet wide, what is the length, in feet?
Amiraneli [1.4K]

Answer:

Step-by-step explanation:

Area = L x W      gym area is (5x + 5x) ft²      if   W = 5x      Find the L

Area = L x W       divide both sides by W

Area/W  = (L x W) / W

Area/W  =  L  =  Area/W

    L = Area/W

       =  (5x + 5x) / (5x)

       =  5x( 1 + 1) / 5x

       =  5x(2) / 5x                      the 5x's cancel each other  5x/5x = 1

       =   2 ft          I got 2.  I suspect the 12 was a typo and should have been 2
