The formula for the perimeter of a rectangle is p=2l+2w. a rectangle has a perimeter of 24 inches. find it’s dimension if it’s lenghth is 3 inches greater than its width

We are given that P = 2l + 2w, P = 24, l = w + 3.
Now, just substitute the information into the formula:

Now, just solve for w:


Now that we have the value for w, plug it back in to the equation l = w + 3




Now, just simplify the fractions: 18/4 = 9/2; 30/4 = 15/2

The width of the rectangle is 9/4. The height of the rectangle is 15/2. Hope this helps and have a significant day!

The answer would be c
