Lisa built a rectangular flower garden that is 4 feet wide and has a perimeter of 26 feet.

What is the length of Lisa's flower garden

Given:

A rectangular flower garden with a;

Perimeter = 26 feet

Width = 4 feet

Length = ?

let, the length of the flower garden be "x"

Now,

We know.

Perimeter of a rectangle = 2 (l + w)

26 = 2 (x + 4)

26 = 2x + 8

26 - 8 = 2x

18 / 2 = x

9 = x

So, the length of the rectangular flower garden is 9 feet.
