Hey there!

"Increased by" means addition, so "Donnie's height increased by 9" means Donnie's height plus 9, so "d + 9". And since it's equal to 74, then "d + 9 = 74". Therefore, your answer is "d + 9 = 74" (Or, it could be d = 74 - 9)

Have a great day!

You may remember that the perimeter of a rectangle is P=2(W+L) where W is the width and L is the length.

s344n2d4d5 [400]

Step-by-step explanation:

So, x=width and the width=13+L. The formula for perimeter is 2(L)+2(W) and the total perimeter in this question is 62 feet. That means 2(L)+2(13+L)=62 feet. Solve for L and that's going to be your length. Add the length plus 13 and you'll have the width. Double check the equation by plugging the width and length back into the equation. (Does that help?)
