Question

if ABCD is a square if the diagonal AC is equal to 4√2 cm find the area of ABCD​

Answer 1

Step-by-step explanation:

the area of ABCD. is 16 sq cm

Answer 2

$area = \frac{1}{2} \times {(diagonal)}^{2} \\ = \frac{1}{2} \times {(4 \sqrt{2} )}^{2} \\ = \frac{1}{2} \times 16 \times 2 = 16$

Hence, area of the square is 16cm²
