A rectangular community garden has an area of $120$ square feet. If the length of the garden is $15$ feet, what is the width of the garden, in feet?

Answer: 8 feet

The area of a rectangle is calculated by multiplying its length by its width (

A = l \times w

). To find the missing width when the area and length are known, you divide the total area by the length (

w = A \div l

). Dividing

120

15

results in exactly

8

feet.

Identify the given values from the problem

Area = 120, Length = 15

To know which values to substitute into the formula for the area of a rectangle.

Apply the area formula for a rectangle

120 = 15 \times w

The formula relates the total area to the length and width: Area = length \times width.

Solve for the unknown width

w = 8

Dividing the area by the length isolates the width variable, giving the final dimension.
