Answer 2

Answer:

The area of the square is equal to 4.205$m^{2}$

Step-by-step explanation:

Given,

The length of diagonal = 2.9m

we know, The diagonal of a square = a$\sqrt{2}$

where a is the side of square.

because, a$\sqrt{2}$ = 2.9m

therefore, a = 2.9/$\sqrt{2}$   metre

Then , the area of square is = Side x Side

                                               = a x a

                                               = 2.9/$\sqrt{2}$  x 2.9/$\sqrt{2}$

                                               = 8.41/2

                                               = 4.205 $m^{2}$

Thus, the area of square is 4.205 $m^{2}$.
