Systems of equations and Inequalities. Last question.

Answer 1

x = 3

Explanation:

Perimeter of the rectangle = 2(l + b)

where l is the length of the rectangle and

b is the breadth of the rectangle.

Here, the perimeter is given to be 18 meters.

And l = 2x m and b = x m

⇒ 18 = 2(2x + x) = 2(3x) = 6x

⇒ x = 3

∴ The value of x is 3 m.
