Question

The length of a rectangular field is 10m more than its breadth. If the perimeter is 80m,find its length and breadth??

Answer 1

Answer:

length=25

breath=15

Step-by-step explanation:

let breadth = x and breadth = x+10

and solve for perimeter

Answer 2

Answer:

The length is 25 m and breadth is 15 m.

Step-by-step explanation:

Given :

Length = 10 m more than breadth

Perimeter = 80 m

To find :

Its length and breadth

Solution :

Let the -

• Breadth = y
• Length = (y + 10)

★ Perimeter = 2(Length + Breadth)

⇒ 2(y + 10 + y) = 80

⇒ 2(2y + 10) = 80

⇒ 2y + 10 = 80/2

⇒ 2y + 10 = 40

⇒ 2y = 40 - 10

⇒ 2y = 30

⇒ y = 30/2

⇒ y = 15

Breadth = 15 m

★ Length -

⇒ 15 + 10

⇒ 25 m

Length = 25 m

Therefore, the length is 25 m and breadth is 15 m.
