Breadth = P/2-length
= 480/2 - 140
= 100
Area = l x b
= 140 x 100
= 14000
= 480/2 - 140
= 100
Area = l x b
= 140 x 100
= 14000

perimeter = 2 (l+b)
480 = 2 (140+b)
240 = 140 + b
b = 100 cm
area of rectangle = l*b
= 140 * 100
= 14000 cm^2
= 140 m^2
480 = 2 (140+b)
240 = 140 + b
b = 100 cm
area of rectangle = l*b
= 140 * 100
= 14000 cm^2
= 140 m^2
