The area of a rectangle is 46 square inches. If the length is 4 times the width, then find the dimensions of the rectangle. Roun
vampirchik [111]

The dimensions of the rectangles to the nearest hundredth are

  • length = 13.56 inches
  • width = 3.39 inches

<h3>What is a rectangle?</h3>

A rectangle is four sided plane figure which each pair of sides equal and opposite to each other. The sides intersect at an angle of 90 degrees.

<u>Given data</u>

Area of the rectangle = 46 square inches

length L = 4 * width W

area of a rectangle, A

A = L * W

46 = L * W

46 = 4w * w

46 = 4w^2

w^2 = 11.5

w = sqrt ( 11.5 )

w = 3.391 inches

w = 3.39 to the nearest hundredth

since L = 4w

L = 4 * 3.391

L = 13.564

L = 13.56 to the nearest hundredth
