Question

Please help! These are composite figures, find the area of the figure and round your answer to one decimal place, if necessary.

Answer 1

297.2190049

Explanation:

Half the 9 gives 4. 5 for the triangle so you have

19x4.5=85.5

Half that because its a triangle not a square and you get 42.75

Then the area of a semicircle is half pi9 squared which is 254.4690049

254.4690049+42.75

=297.2190049
