Question

The length of the diagonal of a square is 30m, find the area of square.​

Answer 1

Answer:

$\mathbf \red{answer}$

450 m^2 will be the Answer.

In a sq., diagonal is given 30m.

We know, Area of a sq. = 1/2d^2

= 1/2 x (30)^2 m^2

= 1/2 x 900 m^2 =

= 450 m^2

Answer 2

Answer:

Area of the square $x^2 = 450 m^2$

Step-by-step explanation:

Let's assume that, the length of the side of the square is x.

According to the problem:

$x^2 + x^2 = 30^2$

$=>2x^2 = 30^2$

∴ $x^2 = \frac{(30).(30)}{2} = (15).(30) = 450$

Area of the square $x^2 = 450 m^2$
