Answer:
78 sqr units
Step-by-step explanation:
Use the Pythagorean Theorem to help find the base opposite the two.
The base of the second parallel line is sqrt( (15^2) - (12^2) ) = sqrt(81) = 9
The second base = 9 + 2 = 11
Area = (b1 + b2)*h/2
h = 12
b1 = 2
b2 = 11
h = 12
Area = (11 + 2)*12/2
Area = 13 * 12/2
Area = 78 square units

Step-by-step explanation:
8.3-7.44=0.86
Answer:
2ab
Step-by-step explanation:
I am pretty sure this is adding polynomials.
This is not correct.
ab-bc+0
ab+bc-ca
0+0+ca
If you take each row at a time, you get.
ab-bc+0
ab+bc-ca
=
2ab+0-ca
0+0+ca
2ab
2ab is your answer
