Answer:
Area of trapezoid = 210 unit²
Step-by-step explanation:
Given:
Height = 12 unit
Parallel side a = 15
Parallel side b = 20
Find:
Area of trapezoid
Computation:
Area of trapezoid = [(a+b)/2]h
Area of trapezoid = [(15+20)/2]12
Area of trapezoid = 210 unit²
Answer:
x = ±11
Step-by-step explanation:
x^2 =121
Take the square root of each side
sqrt(x^2) = ±sqrt(121)
x = ±11
Answer:
(9,21)
Step-by-step explanation:
If you plug in all the pairs, the only one that is true is (9,21).
y=x+12
21=9+12
The above equation is true, and that is why (9,21) is the answer.
Hope this helped! :)
Answer:
the first shape if bigger by 7 so if you were to add 7 to the smaller on on each side you would get the same and equal length and you would not add a cm, m, ft ect because it does not have any information and if you automatically guess that its per say ft youll get the whole answer wrong because ft and cm are 2 way different things but different lengths
