Length is 8feet
Width is 26feet
Step-by-step explanation:
Area of the garden = Length × Width
A = LW
Perimeter = 2(L+W)
If the length of the garden is 8 feet more than 3 times the width, then;
L = 3W+8
Substitute into the second equation
P =2(L+W)
P = 2(3W+8+W)
P = 2(4W+8)
P = 2(4W)+16
If he needs 64 feet of fencing to do the job then;
64 = 8w+16
8w = 64-16
8w = 48
w = 48/8
w = 6feet
Hence the width is 6feet
Get the length
L = 3w+8
L = 3(6)+8
L =18+8
L = 26
Hence the length is 26feet
