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 .
