Question

the perimeter of a rectangle form is 400 and the length is 120 find its breadth​

Answer 1

Answer:

Step-by-step explanation:

P = 2( l + b)

400 = 2( 120 + b) m

200 = 120 + b

b = 200 - 120  

b = 80m

Hence breadth is 80 m.

Answer 2

Answer:

80 units

Step-by-step explanation:

Perimeter=2(l+b)

400=2(120+b)

400/2=120+b

200-120=b

b=80
