Question

The area of a rectangle is 276.9 m². If the length is 15 m, what is the perimeter of the

Answer 1

Answer:

$66.92\:\mathrm{m}$

Step-by-step explanation:

The area of a rectangle is given by $l\cdot w$ where $l$ is the length of the rectangle and $w$ is the width of the rectangle. Therefore, based on the information given, we can write the following equation to solve for the width:

$15\cdot w=276.9,\\w=\frac{276.9}{15},\\w=18.46\:\mathrm{m}$.

The perimeter of a rectangle is given by $p=2w+2l$. Therefore, the perimeter of the rectangle is:

$2(15)+2(18.46)=\fbox{ 66.92\:\mathrm{m} }$.
