Question

The perimeter of a rectangular window is 24 feet. The width of the window is 4 feet more than the length. What are the dimensions of the window?

Answer 1

Perimeter of Window= 24 feet Let length .: width = x+ 4 P = 21 etw) 245 26 2(x + +4) 12 = 2x+y 8 = 20 x=4 Length= 4 feet 8 feet Width

Answer 2

Length = L 

Width = W = L+4

Perimeter = 2(W+L)

                 = 2(L+4+L)

            24 = 2(2L+4)

            12 = 2L+4

             6  = L+2

             4  = L

Length = 4 ft

Width = 4+4 = 8 ft
