Answer:
13.7
Explanation:
the triangle is ... 1/2 b h = 1/2 * 3.6 * 4.8 the semi-circle is ... 1/2 π r^2 = 1/2 * 3.14 * 1.8^2
in other words
What you do is 4.8*3.6=A then divide your answer in half which is the area of the triangle than to find the area of the semi circle you do 3.14*1.8^{2}=A then divide that in half than add the two together then round to the nearest tenth.
