the area of a rectangle is 54 cm. the length is 2 cm more than a x and the width is 5 cm less than twice of x. solve for x. round to the nearest whole number
well, you have to set up an equation.
You should know that length×width will give you the area.
length=2cm more than x (x+2)
width=5cm less than twice of x (2x-5)
so, the equation is (x+2)×(2x-5)=54
Now, just solve for x.
