Question

. The perimeter of a rectangular yard is 18 st.

The length is I foot more than the width. Find the Length & width
equation and solve it.

Answer 1

W=4, L=5

Explanation:

The length is I foot more than the width. Find the Length & width

equation and solve it for a perimeter of 18.

perimeter = 2L + 2W

L=W+1

18=2x(W+1) + 2W

18= 2W +2 +2W =4W +2

4W=18-2=16

W=4 L=W+1 =5

check:

2W + 2L =2X4 +2X5 =8+10 =18
