Answer 2

ill give medel

Answer 3

required area = area pf the base + 4 * area of each triangular side

Answer 4

area of the base = 38^2 because it is a square
and
the area of a triangle = 1/2 * base * height
- just plug in the given measures into this formula

Answer 5

i dont get it :/

Answer 6

which part don't you get?

Answer 7

how do i do the math

Answer 8

well you can first work out 38^2 = 38 * 38 - use ur calculator

Answer 9

it's = 1444

Answer 10

right now the base of each triangle = same as the side of the base = 38 in
and the height is given as 42 in

so the area of one triangle = 1/2 * 38 * 42

Answer 11

798.5

Answer 12

once you do that add 1444 and you get your final ans :)

Answer 13

OMG!!
ITS 1596 NOT 97
SO SORRY

Answer 14

38*42 = 1596

Answer 15

you have also to multiply 798 by since there are 4 triangles in the pyramid

Answer 16

* 798 by 4

Answer 17

after multiplying 798 by 4 add the result to 1444 and you have the answer
