Question

The perimeter of rectangle field is 220 m. If the length of rectangular field is 80 m the qhat will be it's breadth.

Answer 1

Answer:

The breadth of the rectangle is 30 m.

Step-by-step explanation:

Given :

Perimeter = 220 m

Length = 80 m

To find :

Breadth

Solution :

Let the breadth be y

★ Perimeter = 2(Length + Breadth)

⇒ 220 = 2(80 + y)

⇒ 220 = 160 + 2y

⇒ 2y = 220 - 160

⇒ 2y = 60

⇒ y = 60/2

⇒ y = 30

Breadth = 30

Therefore, the breadth of the rectangle is 30 m.

Answer 2

Answer:

As the perimeter of the rectangle 2(l+b)

Step-by-step explanation:

Here length of the field=80m

Perimeter=220m

breadth=?

2(l+b)=220

2(80+b)=220

2*80+2b=220

160+2b=220

2b=220-160=60

So 2b=60

whereb=60/2=30

So the breadtg of the field =30m
