Question

The perimeter of a rectangular box is 950cm if the length of box is 75 cm then it's breadth will be

Answer 1

Answer:

b=400cm

Step-by-step explanation:

Perimeter = 2(l+b)

950cm = 2(75+b)

b = 950 cm /2 -75

b= 475-75

b= 400cm

Answer 2

Given :

• The perimeter of a rectangular box is 950cm if the length of box is 75 cm.

To Find :

• Breadth of rectangular box = ?

Solution :

• Length of rectangular box = 75 cm
• Perimeter of rectangular box = 950 cm

In the question we have given the Length of rectangle and Perimeter of rectangle. And we need to find the Breadth of rectangle. To calculate Breadth of rectangle we have to use formula of perimeter of rectangle 2(Length + Breadth). Let Breadth be 'b'. Now, let's calculate the Breadth of rectangular box. :]

★ According to Question :

→ Perimeter of rectangle = 2(Length + Breadth)

→ 950 = 2(75 + b)

→ 950 = 150 + 2b

→ 950 - 150 = 2b

→ 800 = 2b

→ b = 800 ÷ 2

→ b = 400 cm

Therefore,the breadth of rectangular box is 400 cm.

⠀━━━━━━━━━━━━━━━━━━━━━━━

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

→ 950 = 2(75 + b)

→ 950 = 2(75 + 400)

→ 950 = 2(475)

→ 950 = 950

Hence Verified !
