A = L x W A= 392 and L = 2W 392 = 2W x W 392 = 2W2 392/2 = 2W2/2 196 = W2 14 = W L = 2(W) L = 2(14) L = 28 So the dimensions of a room that has an area of 392 square feet and the Length is twice as big as the width calculates a Length of 28 feet and a width of 14 feet.

The length of a rectangular garden is three feet less than twice the width. If the perimeter of the garden is 82 feet find the dimensions of the garden.?

Let the length be 2x-3 and the width be x:- So: 2*(2x-3+x) = 82 feet => 6x-6 = 82 => x = 14 and 2/3 Therefore the dimensions are: length = 26 ft 4 ins and width = 14 ft 8 ins


Sohan built a rectangular pen for his sheep with an area of 242 square feet He only had 66 feet of fencing to use He wanted the length to be twice as long as the width What were the dimensions of the?

Let the length be 2x and the width be x: 2(2x+x) = 66 the perimeter in feet 4x+2x = 66 6x = 66 x = 11 Therfore: length = 22 feet, width = 11 feet and 22*11 = 242 square feet.

The length of a rectangular field is 75 yards longer than twice the width If the area of the field is 4050 square yards what is the length and width of the field?

Let the length be (2x+75) and the width be x: length*width = area in square yards (2x+75)*x = 4050 2x2+75x-4050 = 0 Solving the above quadratic equation works out as: x = -67.5 or x = 30 it must be the latter because dimensions can't be negative. Therefore: length = 135 yards and width = 30 yards Check: 135*30 = 4050 square yards
