The area of a rectangle is given by the multiplication of both sides of the rectangle. (x-2)×5
It is given that the area will be 30 square units. This means that the above-shown multiplication will be equal to 30 square units. (x-2)×5=30
The value of x is found by putting x in evidence:
x-2=[tex] \frac{30}{5} [/tex] ⇔ x=[tex] \frac{30}{5} [/tex]+2 ⇔ x=6+2 ⇔ x=8
The value of x is 8.
