The perimeter of a rectangle is 90 centimeters the length is 27 centimeters what is the width length of the rectangle?

18 centimeters

Step-by-step explanation:

27(2) = 54

90 - 54 = 36

36/2 = 18

18 centimetres

Step-by-step explanation:

From the question given; The perimeter of a rectangle is 90 centimetres the length is 27 centimetres what is the width length of the rectangle?

To find the width, we are going to follow the steps below:

First write down then formula for finding perimeter of a rectangle

Perimeter of a rectangle = 2l + 2w

where l is the length of the rectangle and w is the width of the rectangle.

From the question given; perimeter = 90 centimetres      and length = 27 centimetres.

We can now proceed to insert our values into the formula;

Perimeter of a rectangle = 2l + 2w

                                  90 =2(27)  +  2w

                                  90 = 54 + 2w

subtract 54 from both-side of the equation

                       90 - 54 = 54 - 54 + 2w

                             36   =  2w

Divide both-side of the equation by 2

                                =  

(At the right-hand side of the equation 2 at the numerator will cancel-out 2 at the denominator, leaving us with just w, while on the left-hand side of the equation 36 will be divided by 2)

                                18 =  w

                                 w = 18 centimetres

Therefore, the width of rectangle is 18 centimetres

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
