length 4x and breadth 3x
3x×4x= 1728
12xsquare = 1728
x square= 1728/12
x= under root 144
x= 12
length= 4×12 = 48 m
breath = 3×12= 36 m
perimeter= 2×(48+36)
2×84= 168 m
cost = 168 × 2.50
= 420 ruppes
3x×4x= 1728
12xsquare = 1728
x square= 1728/12
x= under root 144
x= 12
length= 4×12 = 48 m
breath = 3×12= 36 m
