Question

Area of a square with half diagonal 12

Answer 1

Answer:

288 square units

Step-by-step explanation:

The formula for the area of a square when you know its diagonal is: $\frac{1}{2} d^2$

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. $\frac{1}{2} * 24^2$

Simplify the exponent. $\frac{1}{2} * 576$

Finally, multiply. $288$
