Question

Comparing areas?

Answer 1

`120yd^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`

You can check your answer:
The area of 169 increases by a certain number to get a new area of 289.
We found the increase as 120
`169+120=289`
Therefore, our answer is right

This shows that the area has increased by `120yd^2`
