Let us find the area of the triangle first.
6 x 8 / 2 = 24 ft²
Now we can do the semi circle. Note that it is a semi circle and not a circle.
1/2π(4²) = 8π = 25.12 ft²
Add the areas up to find the area for the figure.
24+25.12 = 49.12 ft²
Answer:
64.80
Step-by-step explanation:
The new price will equal the original price plus the markup.
The markup equal the original price * the markup percentage
markup = 54*.2
markup = 10.8
New price = original + markup
New price = 54+10.8
New price = 64.80
