Answer 1

area of three rectangles=26*5+26*2+26*5.39=?
area of two triangles=\[=2*\frac{ 1 }{ 2 }*5*2=?\]
add the two areas.

Answer 2

Sorry, 10.

Answer 3

\(\huge\color{green}{SA = wh + lw + lh + ls}\)

W=5
L=26
H=2
S=5.39

Answer 4

I used the lateral area formula: p*h where p is the perimeter of the triangular base and h is the height

(2 + 5 + 5.39) * 26 = ? for the lateral area @shaleiah

Answer 5

\(\huge{LA=(a+b+c)h}\)

A=2
B=5
C=5.39
H=26

Answer 6

147.14

Answer 7

To this answer: (2 + 5 + 5.39) * 26 = ? for the lateral area

add 2 times the area of the right triangular base to get the total area of the prism.

Answer 8

147 is not the answer to this: (2 + 5 + 5.39) * 26 =

@shaleiah Try again.

Answer 9

322.14

Answer 10

Correct. 322 when rounded.

Answer 11

The area of the right triangle base is 1/2 * 2*5 = ? @shaleiah

Answer 12

Double what you get for this: 1/2 * 2*5 = ?

because there are 2 bases.

Answer 13

Add 322 to what you get for the areas of the two bases.

Answer 14

Nope.

Answer 15

2 * 1/2 * 2*5 = 10 for the two bases.

What is 10 + 322 ? @shaleiah

Answer 16

332

Answer 17
