Based on the given horizontal and vertical sides of a rectangle and its perimeter, the value of x in the expression is 6
<h3>Perimeter of rectangle</h3>
Perimeter of rectangle = 2(length + width)
- Perimeter of the rectangle = 34 ft
- Length of the rectangle = 3(x - 2) ft
= 3x - 6
- Width of the rectangle = 4x - 7 + (-2x)
= 4x - 7 - 2x
= 2x - 7
Perimeter of rectangle = 2(length + width)
34 = 2{(3x - 6) + (2x - 7)}
34 = 2(3x - 6 + 2x - 7)
34 = 2(5x - 13)
34 = 10x - 26
34 + 26 = 10x
60 = 10x
x = 60/10
x = 6
