Question

what is the area of the rectangle below? select one: a. 45 units² b. 28 units² c. 50 units² d. 40 units²

Explanation:

Step1: Determine length of base

Count the horizontal units from $x = - 3$ to $x=6$. The length of the base $b=6 - (-3)=9$.

Step2: Determine length of height

Count the vertical units from $y=-3$ to $y = 2$. The height $h=2-(-3)=5$.

Step3: Calculate area of rectangle

Use the formula for the area of a rectangle $A = b\times h$. Substitute $b = 9$ and $h = 5$ into the formula: $A=9\times5 = 45$.

Answer:

a. 45 units²
