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?

23

Step-by-step 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

the answer will be

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
