Question

12. (1) The perimeter of a rectangular farm is 400 m and its length is 120 m.find its breadth​

Answer 1

Step-by-step explanation:

perimeter of a rectangle is 2(l+b)

400 = 2(120+b)

400 = 240+2b

2b = 400-240

2b = 160

b = 80

Answer 2

Answer:

Length of the rectangle = 120m

Perimeter of the rectangle= 400m

Breadth of the rectangle=Perimeter/2-Length= 400÷2-120=80
