Use the net to find the surface area of the square pyramid.

A) 152 in2
B) 264 in2
C) 336 in2
D) 448 in2

C)336 in2

Step-by-step explanation:

336 in 2

Area of base → 82 = 64

Area of each triangle →  

1

2

· 8 · 17 → 68

64 + 68 + 68 + 68 + 68 = 336 in2

think about it deeply and passionately about this property

i am sorry

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
