hello could you please help me with this math problem with full explanation which I am unable to solve? Thanks a lot.

Area of a square is side^2

Diagonal of a square is sqrt(2) x side

Using this rewrite the area formula as :

1/2 x diagonal^2

Area = 1/2 x 40^2 = 800

Area = 800 m^2

Answer = b) 800m^2

step-by-step explanation:

mean or average is 40.6
