Question

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth.

Also find the area.​

Answer 1

Step-by-step explanation:

Let length = l

Breadth = b

Perimeter = 2 ( l+b)

= 100 = 2 ( 35 + b )

50= 35+b

50 - 35 = b

b = 15cm

Area = lb

= 35 × 15 = 525cm²

Hope it helps you

Answer 2

Given:-

• Perimeter of the rectangular sheet = 100 cm
• Length of the rectangular sheet = 35 cm

To Find:-

• Breadth of the rectangular sheet
• Area of the rectangular sheet

Solution:-

Perimeter of rectangular sheet = 2(l + b)

=> 100 = 2(35 + b)

=> 100/2 = 35 + b

=> 50 - 35 = b

=> 15 = b

or b = 15 cm

Area of rectangular sheet = l × b

= 35 × 15

= 525 cm²
