Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2
Answer:

Answer:
Step-by-step explanation:
f(x) = 2/3 x + 3
This has the meaning that whatever you see in the backets on the left, you put in the x on the right.
f(12) = 2/3 (12) +3
2/3 12 = 4 * 2 = 8
f(12) = 8 + 3
f(12) = 11
Answer:
Easy think, a square has 4 equal sides and if each side is 400 just multiply 400 x 4 = 1600
