Question

The length of rectangular hall is 3 meters more than double of its breadth.If it’s perimeter is 66 meters, what is its length?

Answer 1

23

Explanation:

Length = 2x + 3

Width = x

Width + Width + Length + Length = Perimeter

Perimeter = 66

This means:

x + x + 2x + 3 + 2x + 3 = 66

6x + 6 = 66

6x = 60

x = 10

The width(x) = 10

The length(2x + 3) = 23
