Answer:
(B) Talia is correct. The lateral area can be found by approximating one large triangle, which can be found using the expression 4 (one-half (8) (6.9))
Step-by-step explanation:
Base of the Pyramid = 8 Inches
Height of the Triangular Face = 6.9 Inches
In any solid shape, the Lateral surface area is the sum of all sides except its top and bottom bases.
Since the four triangles are congruent:
Lateral Surface Area = 4 X Area of One Triangle
Area of a Triangle = 
Area of one Triangular Face 
Therefore:
Lateral Surface Area 
Therefore, Talia is correct.
Four more I hoped this helped :)
5/10 in the lowest fraction is 1/5
The decimal form is 0.5 if you need it
You should use the website Math wa* it helps you will a lot with math only but if you have to pay to see how the computer shows it work and steps to the answer but the answer is free just put the question and you get the answer. It is never wrong I've been using it for 4 years.
*=y so, the * is y at the end of the word
Sorry, I'm going to need a more accurate question. How many kids are there in total?
