The length of a rectangle is five times its width.
if the area of the rectangle is 320 yd^2, find its perimeter.
? yd

ANSWER

96 yd

EXPLANATION

Let the width of the rectangle be w, then, the length of the rectangle will be:

The area of a rectangle is calculated using the formula:

It was given that, the area of the rectangle is 320yd²

Divide both sides by 5.

Take square root of both sides to get:

This means the length is

The perimeter of a rectangle is given by:

P=2(w+l)

We plug in the values to get:

The perimeter is 96yd

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
