Question

The peremetere of a rectangular
room is 242.4 m the width is 50m
What is the length of room?​

Answer 1

Step-by-step explanation:

Width- 50m

Total Perimeter- 242.4 m

Perimeter = 2(l+b)

242.2 = 2(l+50)

242.2 = 2l + 100

2l= 242.2 - 100

2l = 142.2

l = 142.2/ 2

l = 71.1

The length of the room is 71.1

Answer 2

Answer:

Step-by-step explanation:

peremetere of a rectangular  room is 242.4 m

width is 50m

perimeter of rectangle = 2 ( l + b)

                           242.4 = 2 ( l + 50)

                           242.4 = 2l + 100

                           242.4 - 100 = 2l

                          142.4 = 2l

                          l = 142.4/2

                          l = 71.2 m Ans
