Answer 1

It is OC) 11,700 yd.

Explanation:

when finding new area, take you 2 numbers, 52 and 15, square the 15, then multiply them 52 x 15^2 = 11,700

Answer 2

C) 11, 700 yd²

Explanation:

Let
`x` = width of a rectangle

Let
`y` = length of a rectangle

Area of a rectangle = width x length

⇒ area =
`xy`

If a rectangular garden has an area of 52 yd²

⇒
`xy` = 52

If the length and width are multiplied by 15:

⇒ new width =
`15x`

⇒ new length =
`15y`

⇒ area =
`15x * 15y=225xy`

If xy = 52,

new area = 225xy = 225 x 52 = 11700
