Answer 1

Answer:

Area=2400 m²

Perimeter=?

width=40m

let length be'x'

∴Area of rectangle = l * b

                      2400= 40l

                      2400/40= l

                      60=l

∴Length of rectangle is 60 m.

∴Perimeter of rectangle= 2(l+b)

                                       = 2(60+40)

                                       =2*100

                                       = 200 m
