The perimeter of a rectangle is the sum of the lengths of all 4 sides.two sides are lengths and two sides are widths.the perimeter is two lengths plus two widths.you know the perimeter and the length.subtract 2 lengths from the perimeter.that gives you 2 widths.then divide that by 2 to get the width.116 cm - 26 cm - 26 cm = 64 cm64 cm is 2 widths combined.64 cm/2 = 32 cmthe width is 32 cm.check: the perimeter is 26 cm + 26 cm + 32 cm + 32 cm.this adds to 116 cm, which is the perimeter we were given, so our width, 32 cm, is correct.
