Question 282675
The formula for the circumference/perimeter is:

2L + 2W = 10
Remember that L = W + 2<br>
Substitute the value of L for L
2(W + 2) + 2W = 10<br>
Expand:
2W + 4 + 2W = 10<br>
Combine like terms:
4W + 4 = 10<br>
Subtract 4 from each side:
(4W + 4) - 4 = 10 - 4<br>
4W = 6<br>
Divide each side by 4:
4W / 4 = 6 / 4<br>
W = 1 1/2 
L = 1 1/2 + 2 = 3 1/2 <br>
Width = 1 1/2", Length = 3 1/2" and bob's your uncle!
