Question 62

The length of the diagonal of a square is 14 cm. What is area of this square?

Solution

Let the side of square = $$s$$ cm and diagonal, $$d = 14$$ cm

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

=> $$2s^2 = (14)^2 = 196$$

=> $$s^2 = \frac{196}{2} = 98$$

$$\therefore$$ Area of square = $$s^2 = 98 cm^2$$

=> Ans - (C)
