Arectangle has a length of (x+3) centimeters and a width of 1/2x centimeters. if the perimeter is 24 centimeters, what is the length of the rectangle

The length of the rectangle is 9 cm

Step-by-step explanation:

Given: The length of rectangle(l) = (x+3) cm and a width of rectangle (w) = cm a

Also, perimeter of rectangle is 24 cm.

Perimeter of rectangle is to add the lengths of all the four sides.

Perimeter of rectangle (P) is given by;

P=2(l+w)

Substituting the value of P = 24 cm , l = (x+3) cm and w =

then,  

Divide by 2 both sides of an equation;

Combine like terms;

Subtract 3 from both the sides we get;

Simplify:

Multiply both sides by we get

Therefore, length of rectangle(l) = (x+3) = 6+3 = 9 cm

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1
