Which expression represents the total surface area, in square centimeters, of the square pyramid?

A square pyramid. The square base has side lengths of 8.2 centimeters. The triangular sides have a height of 10.3 centimeters.
(8.2) (8.2) + 4 (one-half (8.2) (10.3))
(8.2) (8.2) + 4 (one-half (8.2) (11.1))
(8.2) (10.3) + 2 (one-half (10.3) (10.3)) + 2 (one-half (8.2) (10.3))
(8.2) (10.3) + 2 (one-half (10.3) (11.1)) + 2 (one-half (8.2) (11.1))

(A)

Step-by-step explanation:

A Square Pyramid has a Square Base and 4 triangular faces.

The Surface Area of a Square Pyramid=Area of Square Base+Area of the 4 Triangular faces

Side Lengths of Square Base=8.2cm

Height of the Triangular faces =10.3cm

Therefore:

Area of the Square Base

Area of one Triangular Face

Therefore:

Area of the Pyramid

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)

i suppose it should be (y=2x-5)
