Find the surface area of the pyramid.

a. 64 in.2

b. 56 in.2

c. 88 in.2

d. 118 in.2

I believe it may be A.

Step-by-step explanation:

The formula looks complicated so I'm going to simplify it.

SA = 1/2 (4 * side of base * height) + side of base^2

Using this, we can get our answer.

1/2 (4 * 4 * 6) + 4^2

1/2 * 96 + 16

48 + 16

64

Thus the answer should be 64in. ^2

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
