A rectangle has a width of 3 inches. The rectangle's length is 5 times it's width. What is the area of the the rectangle

Since the area formula for a rectangle is A=lw, A meaning area, l equal to length, w equal to width, you need to use the formula.

Since the rectangle's length is 5 times the width, you need to use 5w instead of l.

And the width is 3 inches.

3 x 5 equals 15.

The length is 15 inches.

Now, plug in the equation,

A = 15 x 3

The area of the rectangle is 45 inches.

The area for the rectangle is 45 inches
