The perimeter of a square is 90 cm more than the length of each of its side. What is the length of each side of the square?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option B i.e 30 cm
Let's assume the length of each of its sides is 'y'.
The perimeter of a square is 90 cm more than the length of each of its sides.
4y = 90 + y
4y - y = 90
3y = 90
y = 30
Length of each side of the square = 30 cm
