Question

Area of a square with half diagonal 12

Answer 1

288 square units

Explanation:

The formula for the area of a square when you know its diagonal is:
`(1)/(2) d^2`

So, since we know the half diagonal is 12, we need to multiply that by 2 to get the diagonal, which is 24.

Put 24 into the formula.
`(1)/(2) * 24^2`

Simplify the exponent.
`(1)/(2) * 576`

Finally, multiply.
`288`
