Question

the length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle. show how you got your answer?

Answer 1

42-6=36
36 divided by 4= 9
By this point there are 9 inches on each side.
Take one nine and add three
Do this twice
So the problem should look like this
3+3=6 42-6=36 36 divided by 4= 9 9+3=12 9+3=12
Perimeter = 12+12+9+9=42
