Question

the length of rectangle is 2cm more than its breadth.if the perimeter of the rectangle is 28cm.find the length​

Answer 1

Answer:

let the breadth of rect. be x

and length be x+2

given perimeter of rectangle = 28

perimeter of rectangle= 2(l+b)

so, 28 = 2(x+2+x)

28/2 = 2x+2

14 - 2 = 2x

12 = 2x

so, x = 12/2 = 6 CM

length of rectangle = x+2 = 6+2 = 8 CM

breadth of rectangle = 6 cm

I hope it will help you

Answer 2

Given:-

• Length of a rectangle is 2 cm more than its breadth.
• Perimeter of a rectangle is 28 cm.

⠀

To find:-

• Length of a rectangle.

⠀

Solution:-

Let,

• the breadth of a rectangle be x.
• the length of a rectangle be x + 2.

⠀

According to the question

★Formula used:-

Perimeter of rectangle = 2(length + breadth)

⠀

→ 28 = 2(l + b)

→ 28 = 2(x + x + 2)

→ 28 = 2(2x + 2)

→ 28/2 = 2x + 2

→ 14 = 2x + 2

→ 14 - 2 = 2x

→ 12 = 2x

→ x = 12/2

→ x = 6

⠀

Therefore,

• Breadth = 6 cm
• Length = x + 2 = 6 + 2 = 8 cm

⠀

Hence,

• the breadth of a rectangle is 6 cm and length of a rectangle is 8 cm.
