96

Step-by-step explanation:

Triangles (front and back)

There are two right triangles -- front and back.

One triangle = 1/2*h*b

h = 3

b = 4

One triangle = 1/2 * 3 * 4

One triangle = 6

two triangles = 2*6 =12

Rectangle using the Net

Area = L * W

L = 3 + 4 + 5 = 12

W = 7

Area = 12 * 7 = 84

Total Area

Area = 12 + 84

Area = 96

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

3+x
