The net below can be folded to form a square pyramid.
What is the surface area of the pyramid?

Surface area of the square pyramid = 217.8 in²

Solution:

Side length of the square = 9 in

Area of the square = side × side

                                = 9 in × 9 in

                                = 81 in²

Area of the square = 81 in²

Perimeter of the base = 4 × 9 in = 36 in

Slant height of the triangle = 7.6 in

Surface area of the square pyramid

                            = 217.8 in²

Surface area of the square pyramid = 217.8 in²

y-1700=200(x+4)

step-by-step explanation:

200(x+4) is 200x + 800 she is saving 200 per week x is the weeks and the -1700 is. us that’s howmuch she already had

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
