Answer 1

Answer:
`A=16c^2+32cd+16d^2`

Explanation:

The formula for area of a square is
`A=l*w`, where A is area, l is length, and w is width. Since all sides of a square is equal, we just multiply 4c+4d by itself.

`A=(4c+4d)*(4c+4d)` [distribute]

`A=16c^2+16cd+16cd+16d^2` [combine like terms]

`A=16c^2+32cd+16d^2`

Therefore, the area is
`A=16c^2+32cd+16d^2`.
