P = 2l + 2w

l = 2w + 8

P = 136

136 = 2l + 2w

136 = 2(2w+8) + 2w

136 = 4w + 16 + 2w

136 = 6w + 16

120 = 6w

w = 20

l = 2(20) + 8

l = 40 + 8

l = 48

CHECK:

136 = 2l + 2w

136 = 2(48) + 2(20)

136 = 96 + 40

136 = 136

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.)

4cm by 13cm

The dimensions of the rectangle are 21 units by 9 units

15m wide and 31m long

The area is 72 The dimensions would be 6x12 6 * 2 + 12 * 2 = 36

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 dimensions of the rectangle are 21 units by 9 units

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

width=15 length=35

The dimensions work out as length 15 units and width 8 units Check: 2*(15+8) = 46 units which is its perimeter

twice length + twice width = perimeter In this example, L= 3W 2(3W)+2(W)=64 8W=64 W=6 L =3W L=18 The dimensions of this rectangle are: 18 by 6

15m wide and 31m long
