Question

If the perimeter of rectangle is 120 metre and its length is 35 then find its breadth

Answer 1

Step-by-step explanation:

perimeter of a rectangle = 2(l + b)

=> perimeter = 2(35 + b)

=> 120 = 70 + 2b

=> 120- 70 = 2b

=> 50 = 2b

=>50/2= b

=> breadth = 25

Answer 2

Answer:

The breadth of the rectangle = 25 m

Step-by-step explanation:

GIVEN

• The Perimeter of a rectangle = 120 m
• Length of the rectangle = 35 m

Let us assume that the breadth of the rectangle be x m.

TO FIND

• The breadth of the rectangle.

FORMULA USED

• Perimeter of a rectangle = 2(Length + Breadth)

APPLYING THE FORMULA OF PERIMETER

Perimeter of a rectangle = 2(Length + Breadth)

→ 120 = 2(35 + x)

→ 35 + x = 120/2

→ 35 + x = 60

→ x = 60 - 35

→ x = 25

∴ Breadth of the rectangle = x = 25 m
