# Comparing areas?

Dec 2, 2017

$120 y {d}^{2}$

#### Explanation:

I’m going to assume that you understand how to do the first two portions of the question (since you got it right)- if you need an explanation on how you got there, just comment/msg me.

To find the increase of the area, you have to subtract the new area from the initial area.

$289 - 169 = 120$

$169 + 120 = 289$
This shows that the area has increased by $120 y {d}^{2}$
