Question

A rectangle has width that is 3 meters more than twice its length. if the perimeter of the rectangle is 186 meters, what is the length of the rectangle?

Answer 1

let the length be y.
2y + (2y+3) x 2 = 186
2y + 4y + 6 = 186
6y + 6 = 186
6y = 180
y = 30
so the length is 30 meters

Answer 2

The length of the rectangle is 30 meters.

What is perimeter of rectangle?

Perimeter of the rectangle is defined as addition the lengths of the rectangle's four sides.

Perimeter of the rectangle equation is 2(a + b)

Where, a is length of the rectangle and b is width of rectangle.

What is area of the rectangle?

Area of the rectangle is defined as product of the length and width of the rectangle.

Formula of area of the rectangle is length × width

Given data as :

Rectangle has width that is 3 meters more than twice its length.

Perimeter of the rectangle is 186 meters,

Let the length of rectangle be x .

Perimeter of rectangle equation is 2(a + b)

Substitute the values in above equation,

2x + (2x+3)× 2 = 186

2x + 4x + 6 = 186

6x + 6 = 186

6x = 180

x = 30

Hence, the length of the rectangle is 30 meters.
