Question

A right triangle is removed from a rectangle to create the shaded region shown below. Find the area of the shaded region. Be sure to include the correct in
your answer

Answer 1

Answer:

59.5 cm

Step-by-step explanation:

Find the area of the entire rectangle first. Formula is base times height: $9*8$

=72

Next, find the missing sides by subtracting $8-3$ and $9-4$.  

=5 and 5

Then find the area of the triangle. Formula is base times height divided by 2: $\frac{5*5}{2}$

=12.5

Then subtract to find only the shaded section: $72-12.5$

=59.5 cm
