Question

The perimeter of a small rectangular garden is 14 feet. If the length is thrice the width, find the width and length of the garden.

Answer 1

Answer:width=1.75feet Length=5.75feet

Explanation:

perimeter(p)=14feet

Length(L)=3xwidth(w)

L=3 x w

P=2xL+2xw

14=2xL + 2xw

Substitute L=3 x w in 14=2xL+2xw

14=2 x 3 x w +2 x w

14=6w+2w

14=8w

Divide both sides by 8

14 ➗ 8=8w ➗ 8

1.75=w

Width=1.75feet

Substitute w=1.75 in L=3 x w

L=3x1.75 L=5.25

Length=5.25feet
