13. A rectangle has a width that is twice as long as its length and an area of 722 square inches. Find the length of the diagona
LekaFEV [45]

Answer:

The diagonal of the rectangle is approximately 42.5 inches.

Step-by-step explanation:

The area of a rectangle is given by the following formula:

area = width*length

In this case the width = 2*length, therefore we have:

area = 2*length²

722 = 2*length²

2*length² = 722

length² = 361

length = sqrt(361) = 19 inches

width = 2*length = 2*19 = 38 inches

The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:

diagonal = sqrt(length² + width²)

diagonal = sqrt(19² + 38²) = 42.485 inches

The diagonal of the rectangle is approximately 42.5 inches.
