The length of a rectangle is 4 less than three times its width. The perimeter is 72 feet. So, the dimensions of the rectangle are 10 and 26.
The perimeter of a rectangle is defined as the sum of all the four sides of the rectangle.
The perimeter of a rectangle = 2( l + b)
The length of a rectangle is 4 less than three times its width. The perimeter is 72 feet.
Let's consider width equals x.
Length = 3x - 4
Solve for x:
[tex]72 = 2(3x - 4) + 2x\\72=6x-8+2x\\80=8x\\X=10[/tex]
So, width = 10
Length= 3(10) - 4 = 26
