The rectangle below is composed of two smaller rectangles.
Calculate x given that the perimeter of rectangle AEFD is 30.
The rectangle below is composed of two smaller rectangles.
Calculate x given that the perimeter of rectangle AEFD is 30.
To solve the problem, we'll begin by setting up the equation for the perimeter of rectangle :
The perimeter of a rectangle is given by the formula:
We're told that the perimeter of rectangle is 30. The length is and the width is . Thus, the perimeter equation is:
Let's simplify the expression inside the parentheses:
So the equation becomes:
Now, distribute the 2:
Subtract 10 from both sides of the equation:
Divide both sides by 2 to solve for :
Therefore, the value of that satisfies the given perimeter is .
