The length of a rectangle is twice its width. The perimeter of the rectangle is 24 inches. Write a system of equations in 2 variables. Use substitution to solve the problem.
Equation 1:
Equation 2:
What is the area of the rectangle?
the width can be x. so it means that the length is 2x the equation would be 2(x+2x)=24 inches 2x+4x= 24 6x= 24 x=4 (this is the width, so the length will be 8 inches) the area will be 4 times 8 = 32
