Answer:
A) 147.6 sq m
Step-by-step explanation:
Separate the pyramided out into 4 triangles and add those
3 of them (sides) will be the same

This is one half of the side, multiply by 2 to get the area of the entire side, 40 square m.
The area of all 3 sides together is 40*3 = 120 sq m
For your base, your height will be 6.9 and your base is 4
A = 13.8 sq m
multiply by 2 again for the entire base
A=27.6 sq m
Now add both
120 + 27.6
The solution to the question how much was the total cost for the seminar is shown below:
Cost 1 = $ 340 for the total wages for the group
cost 2 =$5 x 5 employees, this is for the refreshments
cost 3 = $75 for the instructors fee
cost 4 = $250 for the supplies and others
Total cost = cost1 +cost2 +cost3 + cost 4
Total cost = $340 + ($5*5) + $75 + 250
Total cost = $690
