Question

The perimeter of a rectangle is 50meter .and one of it's side is 15meter. How many meter is the other side?

Answer 1

Answer:

20 m

Step-by-step explanation:

perimeter = 50 m

perimeter = 2 x l + b

2 X l + b = 50

2 x 15 + b = 50

30 + b = 50

b = 50 - 30

b = 20 m

Answer 2

Hey friend!! Here is your answer-:

Step-by-step explanation:

Perimeter of rectangle= 50m

One side (breadth) of rectangle=15m

Let the other side (length) of rectangle be x meters.

Perimeter of rectangle= 2(length+breadth)

50 = 2(length+15)

50÷2 = length+15

25 = length+15

25-15 = length

10 meters = length

So the length of other size of the rectangle is 10m.
