Question

Can someone help me find the lateral area??

The slant height of a regular pentagonal pyramid is 8 cm and the length of each side of the base is 4 cm.
What's the lateral area?

a. 32 square cm
b. 60 square cm
c. 80 square cm
d. 160 square cm

I think it's C. Am I right?

Answer 1

so area AVB = 4*8/2 = 16

than multiplie this area by 5 and will get the lateral area what will be 5*16 = 80 cm^2

hope that you understand it sure

Answer 2

thank you so much!
