The length of a rectangle L is 5 centimeters greater than its width W.
L=W%2B5cm
The perimeter P is 58cm.
P=2%28L%2BW%29....substitute L=W%2B5cm and P=58cm
58cm=2%28W%2B5cm%2BW%29
58cm=2%282W%2B5cm%29
58cm=4W%2B10cm
58cm-10cm=4W
48cm=4W
48cm%2F4=W

highlight%2812cm=W%29...now find L
L=W%2B5cm
L=12cm%2B5cm
highlight%28L=17cm%29
