Question : 42

Total: 50

The length of the diagonal of a square is 12 cm. Calculate the area of the square.

$36 cm^2$
$48 cm^2$
$72 cm^2$
$18 cm^2$

Solution:

Let each side be l, then area = $l^2$

Using Pythagoras theorem

l^2 + l^2 = 12^2

2l^2 = 144

divide both sides by 2

l^2 = 72

Therefore, the Area of the square is $72 cm^2$
