Answer:
56
Step-by-step explanation:
A∆ = BH/2
Area of a parm is BH (base x height) so we multiply area of triangle by 2.
28 x 2 = 56. There you go
The answer is b)35 because those angles are supplementary which means their sum is 180.
so 180+145 = 35
Answer:
-4x-18
Step-by-step explanation:
pickle
LA = (2l + 2w)h
Plug in what we know:
LA = (2(11) + 2(7))(4)
Multiply:
LA = (22 + 14)(4)
Add:
LA = 36(4)
Multiply:
LA = 144
