Three minutes and you're begging?? Wow ... you need to develop some patience or something.
If one side of a rectangle is 11 cm long, the opposite side is also 11 cm. So they account for 22 cm.
What is the result of 42 - 22?
Divide that number by 2 in order to find the length of each of the shorter sides.

Divide that number by 2 in order to find the length of each of the shorter sides.
2L + 2W = 42
2*11 + 2W = 42
2W = 20
W = 10
L = 11
2*11 + 2W = 42
2W = 20
W = 10
L = 11
