Question

What is the lateral area of the pyramid?

Answer 1

Explanation:

Alright, lets get started.

The lateral area will be the area of all 4 sides.

The two sides have base length 11 feet and height of 11.9 feet.

The area of this side is :
`(1)/(2)*base*height`

The area of this side is :
`(1)/(2)*11*11.9=65.45`

The two sides have base length 9 feet and height 12.3 feet.

The area of this side is :
`(1)/(2)*9*12.3=55.35`

All 4 sides area will be :
`2(65.45+55.35)`

All 4 sides area = 241.6 square feet

Hence the lateral area will be 241.6 square feet : Answer B

Hope it will help :)

Answer 2

9*12.3 = 110.7

11*11.9 = 130.90

130.90 + 110.70 = 241.6 ft^2
