Answer 1

So let's think about the Lateral area first

Answer 2

Alright

Answer 3

Lateral Area is the area of the figure without its bases

Answer 4

this figure has 1 base

Answer 5

but the lateral area is consisting of the area of 2 triangle and 2 rectangles
Hint: recall the area of Triangle and rectangles then add the area you got to get the lateral area

Answer 6

I got 361.08

Answer 7

I am sorry for this mistake. I forgot
This triangular prism has a special case
where The Lateral area of it = Perimeter of the base * height

Answer 8

check it out and tell me what you got

Answer 9

Have you done it ?

Answer 10

hint perimeter of the base is the sum of triangle's sides

Answer 11

I got 784!!! :)

Answer 12

well done So, let's find the surface area

Answer 13

we have the L.S.A (Lateral surface area)
and the Total surface area = L.S.A + area of the bases

Answer 14

since we have one base

we will find it's area and add it to the lateral surface area

Answer 15

856

Answer 16

how did you get it?

Answer 17

72+784

Answer 18

well done, note that 72 come from the 1/2 * base * height and since we have 2 bases so 2(area of one base)

Answer 19

Great well done
