Question

Find the aerea of the square the length of whose diagonal is 2.4m

Answer 1

diagonal = side of square*(sqrt[2])
side = d/[sqrt(2)]

area = side^2 = (d/[sqrt(2))^2 
                        = (d^2)/2
                        = (2.4)^2  / 2 m^2
                        = 5.76/2m^2
                        = 2.88m^2

Answer 2

Answer:

hiii

a= a2

d= √2a

a=1by2 d^2 =1by2 . 2.4^2 = 2.88m^2..

..... plz mark me...........
