Question

Find the area of a square whose diagonal is 5√2cm. Hint - Area = [1/2×(diagonal)square] sq units

Answer 1

Area = 1/2×(diagonal)square
= 1/2×5root2square
=1/2× 50
= 25 cm square

Answer 2

We know that diagonal of square are equal
therefore
d1 = d2 = 5 root 2 cm

area of square =
1/2 × d1 × d2
1/2 × (5 root2)^2
1/2 × 50
25 cm ^2
