Question

The breadth of a rectangle having perimeter 70 m and length 20 m is
cm.
A. 15
B. 30
C. 14
D. 40
​

Answer 1

Answer:

$\huge\bf\red{Answer}$

• perimeter = 70 m

• length = 20 m

perimeter of rectangle = 2×(l+b)

➡️ 70 = 2×(20+b)

➡️ 70 = 40 + 2b

➡️ 70 - 40 = 2b

➡️ 2b = 30

➡️ b = 30/2

➡️ b = 15

Therefore breadth = 15 m.

Answer 2

Answer:

15

Step-by-step explanation:

Perimeter of rectangle= 2(length+breadth)

70 = 2(20+breadth)

70/2 = 20 + breadth

35-20 = breadth

15 = breadth
