Answer 2

The area increases from 81 yd² to 256 yd², which is an increase of 175 yd².

Explanation:

We need to find the area of the first square and the square after the expansion.

Area of square with side 9yd = 9 × 9

= 81 yd²

Area of square with side 9+7yd = (9+7) × (9+7)

= 16 × 16

= 256 yd²

Difference = 256 yd² - 81 yd²

= 175 yd²
