find the breadth of the rectangle whose length is 70cm
& Perimeter 200cm.​

Answer 1

Answer:

Given :-

• A rectangle whose length is 70 cm and perimeter is 200 cm.

To Find :-

• What is the breadth of the rectangle.

Formula Used :-

➲ Perimeter of a Rectangle = 2(Length + Breadth)

Solution :-

Given :

• Length = 70 cm
• Perimeter = 200 cm

According to the question by using the formula we get,

↦ 2(70 + B) = 200

↦ 140 + 2B = 200

↦ 2B = 200 - 140

↦ 2B = 60

↦ B = 60/2

➠ B = 30 cm

∴ The breadth of a rectangle is 30 cm.

VERIFICATION :-

⇒ 2(Length + Breadth) = 200

By putting Breadth = 30 we get,

⇒ 2(70 + 30) = 200

⇒ 2(100) = 200

⇒ 2 × 100 = 200

➦ 200 = 200

Hence, Verified .
