.iiiiiiiiiii dooooonnntttttt kkkkknnnooowww
First find the area of the triangle,
(8.4 x 24)/2 = 100.8
Then find the area of the parallelogram,
24 x 12 = 288
Then add both,
100.8+288 = 388.8 yd^2
When simplifying you add exponents that appear in the numerator and subtract those that appear in the denominator.
Now negative exponents can be put in the denominator as positive exponents.
This corresponds to selection
