Answer:width=1.75feet Length=5.75feet
Step-by-step 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
