A rectangle has two dimensions, length and width. You haven't said what the width is. The perimeter is the distance around the rectangle. Imagine going round it. You would go 42 inches, then a width, then another 42 inches, then another width. In general, the perimeter of a rectangle is twice its length plus twice its width.

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

2 (x + 2x) = 42 x + 2x = 21 3x = 21 Therefore, x = 7 The width of the rectangle is 7 inches. The length of the rectangle is 14 inches.

The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar

The length of a rectangle is twice its width. If the perimeter of the rectangle is , find its area.

If the length of a rectangle is twice its width and it has a perimeter of 48, then the rectangle is 16 in length and 8 in width.

The perimeter of a rectangle is twice the sum of the width and length: perimeter = 2 x (4.6in + 12.1 in) = 33.4 in

2 (x + 2x) = 42 x + 2x = 21 3x = 21 Therefore, x = 7 The width of the rectangle is 7 inches. The length of the rectangle is 14 inches.

Area is length times width, perimeter is twice the sum of length and breadth.

Do-it-in-your-head method: Length + width is half the perimeter which is 27 inches; 27 minus 6 is 21 and one-third of 21 is 7 which is the width. (Length = 2 x 7 + 6 = 20)

The perimeter of a rectangle is 42. Meters. The length of the rectangle is threemeter less than twice the width.Mar

If you increase the rectangle's length by a value, its perimeter increases by twice that value. If you increase the rectangle's width by a value, its perimeter increases by twice that value. (A rectangle is defined by its length and width, and opposite sides of a rectangle are the same length. The lines always meet at their endpoints at 90° angles.)

Length = (Perimeter - twice width) / 2

Perimeter of a rectangle = twice (length + width), in this case 22 m.
