A = (b*h)/2

A = (4.8*1.7)/2

A = ???

Answer 17

I recommend writing down each area and perimeter formula on a note sheet so you can look them up quickly

Answer 18

4.08

Answer 19

good, now multiply that by 4

afterwards, add that to 2.89

Answer 20

19.21

Answer 21

perfect

Answer 22

yay!

Answer 23

you got 16.32 for the lateral surface area

2.89 was the base area

Answer 24

ohh okai

Answer 25

so

total surface area = base area + lateral surface area

total surface area = 2.89 + 16.32

just summing things up (you probably already know by now)
