Answer 1

Answer:

let,the length of the rectangle be x And Breadth x-5. A/Q ,2(x+x-5) =30m 2(2x-5)=30. 2x-5 =30/2. 2x-5=15. 2x=15+5. 2x=20. x=20/2. therefore,x=10

Step-by-step explanation:

hope it helps!!!

Answer 2

Given :

• The breadth of a rectangle is 5 less than its length. If the perimeter is 30 metre.

To Find :

• Length of rectangle = ?
• Breadth of rectangle = ?

Solution :

• Perimeter of rectangle = 30 m

• Let Length of rectangle be 'x' and Breadth of rectangle be 'x - 5'.

★ According to Question now :-

→ Perimeter of rectangle = 2(Length + Breadth)

→ 30 = 2(x + x - 5)

→ 30 = 2(2x - 5)

→ 30 = 4x - 10

→ 30 + 10 = 4x

→ 40 = 4x

→ 4x = 40

→ x = 40 ÷ 4

→ x = 10 m

Hence,

• Length of rectangle = x = 10 m
• Breadth of rectangle = x - 5 = 10 - 5 = 5 m

⠀━━━━━━━━━━━━━━━━━━━━━━━

V E R I F I C A T I O N :

➻ 30 = 2(x + x - 5)

➻ 30 = 2(10 + 10 - 5)

➻ 30 = 2(10 + 5)

➻ 30 = 2(15)

➻ 30 = 30

Hence Verified !
