Question

A rectangle has a width of six units and the length of 2X +8 units. If the area is 108 units squared, what is the value of X?

Answer 1

Width of rectangle = 6 units

Length of rectangle = 2X+8 units

Area = 108 units square

Area = length * width

$108=6(2x+8)$

$108=12x+48$

$12x=60$

$x=5$ units
