Answer» 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 .

Answer:

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

Given :

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.

⇒ 2(Length + Breadth) = 200

By PUTTING Breadth = 30 we get,

⇒ 2(70 + 30) = 200

⇒ 2(100) = 200

⇒ 2 × 100 = 200

➦ 200 = 200

Hence, Verified .
