Question

find the area of the square whose diagonal are 5.2
​

Answer 1

Step-by-step explanation:

1. Diagonal of Square = side of square × 2^1/2
2. so,

5.2 = a × 1.414 ( 2^1/2 = 1.414)

a = 5.2 ÷ 1.414

=3.67

• Area = side ^2
• =3.67^2

=13.6

Answer 2

Answer:

Let side of square be x . then length of diagonal will be x√2 .

$x \sqrt{2} = 5.2 \\ x = \frac{5.2}{ \sqrt{2} }$

And area of square

$= {x}^{2} = \frac{5.2 \times 5.2}{2} = 13.52 \:$
