Riley is building a garden box for his backyard. He wants the perimeter to be 32 ft long. If
MA_775_DIABLO [31]

Answer:

Length of the garden = 10 ft

Step-by-step explanation:

Perimeter of a garden = 2(length + width)

Perimeter of the garden = 32 ft

Width of the garden = 6 ft

Length of the garden = x ft

Perimeter of a garden = 2(length + width)

32 = 2 ( x + 6 )

Open parenthesis

32 = 2x + 12

Subtract 12 from both sides

32 - 12 = 2x + 12 - 12

20 = 2x

Divide both sides by 2

20 / 2 = 2x / 2

10 = x

x = 10 ft

Therefore, length of the garden = x = 10 ft
