Question

The perimeter of a rectangle is 25 m and one of its sides is 5 m. What is the length of the other side?

• A. 5 m
• B. 7.5 m
• C. 9 m
• D. 10.5 m

Answer 1

The correct option is B 7.5 m

Let,
the other side be x.
2(5+x) = 25
10 + 2x = 25
2x = 25 - 10
2x = 15
x = 15/2
x = 7.5

Thus, the length of the other side is 7.5 m.
