The length of a rectangle is 4 inches more than its width, and its perimeter is 36 inches. find the width of the rectangle.

a.) 6 in.
b.) 11 in.
c.) 7 in.

Let w be the width of the rectangle. From the given condition above, its length is therefore equal to w + 4. The perimeter (P) of the rectangle is twice the sum of its width and length. With the given,
                                 36 in = 2 x (w + w + 4)
The value of w is 7. The length is therefore 11 inches. 

Multiply 9 and 67. then multiply 3 with 67. lastly the answer that you got for 9x67 is to be subtracted by the answer you got for 3x67
