First, find the area of the rectangle. The formula is already given, and the length and width is shown on the 'beautiful drawing'.
The area of the rectangle is 171cm².
Find the area of the triangle. We see that it fits perfectly inside the triangle with some space to spare. It has the same height, so we have our 'h' value. Because there are 4cm and 3cm left for the width, subtract the sum of these numbers from the width.
, so the base of the triangle is 5cm long (remember that the figure isn't drawn to scale. I almost missed this one).
Final step. Subtract the area of the triangle from the rectangle: .
The area of the shaded region is 148.5cm².

Answer:
C. A chart displaying the amount of care pets require.
Step-by-step explanation:
(A). A picture of common house pets.
This wouldn't be effective since everyone knows what most common house pets look like.
(B). A picture of common pet supplies.
This wouldn't be effective since pet supplies vary with every animal.
(C). A chart displaying the amount of care pets require.
This would be the best choice since the image would show the required necessities for each different pet.
(D). A chart displaying which pets are the most popular.
This wouldn't be effective since popularity is mostly based on preference.
The area of a circular segment is given by
.. A = (1/2)r^2*(θ -sin(θ)) . . . . . . . . . θ in radians
.. = (1/2)*(27.8 in)^2*(5π/6 -sin(5π/6))
.. ≈ 818.4 in^2
