If a rectangle has the area of 450, and the length is two times the width. what is the length and width?

Answer 1

The area (A) of a rectangle is calculated by multiplying the length (l) by the width (w).

If we use the variable w to represent the width of the rectangle, then we can write:

A = l • w

In this problem, the length is equal to two times the width or 2w

Then A = 2w • w

We can solve for w using the area of 450:

A = 2w• w

A = 2w ²

450 = 2w ²

450 / 2 = 2w ² /2

225 = w²

w will be the square root of 225 or 15:

15 = w

The width will be 15 units.

The length will be two times the width or 2 • 15 = 30 units.
