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:
I do not agree with him.
Step-by-step explanation:
even though 20 has no visible decimal digits it has an infinite amount of zeros in the decimal digits. since 1.97 has two digits, then we can just write 20 as 20.00
