PLS HELP!! Note: Figure is not drawn to scale.

If a = 13 cm, b = 7 cm, and c = 3 cm, what is the surface area of the geometric shape formed by this net?

99

Step-by-step explanation:

(b)(c) = 21

SInce there are 2 triangles with an area of 21, multiply that by 2 and divide it by 1/2.

(c)(a) = 39

Do the same thing

(a)(c) = 39

add everything up

21 + 39 = 60

60 + 39 = 99

Hope this helps!

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
