Question

8.
The perimeter of the floor of a rectangular
hall is 24 m. Its length is 7 m. Find its
breadth​

Answer 1

Answer:

PERIMETER=2(L+B)

24=2(7+B)

24=14+2B

2B=24-14

B=10/2

B=5

Answer 2

Answer:

The breadth is 5cm.

Step-by-step explanation:

The perimeter of floor rectangle: 2×(l+b)

= 2×(7+2b)

= 2×7

= 14

breadth = 24 - 14

= 10 ÷ 2

= 5cm.
