Question

The perimeter of a rectangular yard is 14 ft. The length is 1 foot more than the width. Find the length and the width of the yard.

Answer 1

width (w): x

Length (L): x + 1

Perimeter = 2(L) + 2(w)

            14 = 2(x + 1) + 2(x)

            14 = 2x + 2 + 2x

            14 = 4x + 2

            12 = 4x

             3 = x

Length: x + 1  = (3) + 1  = 4

Answer: width = 3, length = 4

Answer 2

Answer:

x=5

Step-by-step explanation:

30=x+2x+3x=6x

x=5
