Question 59

If the diagonal of a square is 10 cm, then what is the area $$(in cm^2)$$ of the square?

Solution

Let side of square = $$s$$ cm and diagonal = 10 cm

=> $$s^2+s^2=(10)^2$$

=> $$2s^2=100$$

=> $$s^2=\frac{100}{2}=50$$ -------------(i)

$$\therefore$$ Area of square = $$s^2=50$$ $$cm^2$$

=> Ans - (C)
