The rectangle below has an area of x^2-144x
2
−144 square meters and a length of x+12x+12 meters.
what expression represents the width of the rectangle?

width = x - 12

Step-by-step explanation:

Area = x² - 144 ← difference of squares

x² - 144 = (x + 12)(x - 12) ← in factored form

Area = length × width

length = x + 12 ⇒ width = x - 12

43

step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
