Question

The perimeter of the rectangular field is 480m.if it's length is 80m, then find its bteadth

Answer 1

Perimeter = 480 m

Length = 80m

As we know

Perimeter =2*(l+b)

So breadth=

480=2*(80+b)

480/2=80+b

240=80+b

240-80=b

160=b

Answer 2

Answer:

breadth is 160 m

Step-by-step explanation:

Given,

length= 80m

breadth= ?

Perimeter = 480m

As we know perimeter

=> 2(l+b) =480

=> 2(80 + b) = 480

=> 80 + b = 480/2

=> b = 240-80

=> b=160
