What is the lateral area of the pyramid?

9*12.3 = 110.7
11*11.9 = 130.90
130.90 + 110.70 = 241.6 ft^2
Answer:
Step-by-step 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 : [tex]\frac{1}{2}*base*height[/tex]
The area of this side is : [tex]\frac{1}{2}*11*11.9=65.45[/tex]
The two sides have base length 9 feet and height 12.3 feet.
The area of this side is : [tex]\frac{1}{2}*9*12.3=55.35[/tex]
All 4 sides area will be : [tex]2(65.45+55.35)[/tex]
All 4 sides area = 241.6 square feet
Hence the lateral area will be 241.6 square feet : Answer B
Hope it will help :)
