Answer :
1. What is the lateral surface area of a square pyramid with side length 11.2 cm and slant height 20 cm?
224 cm2
448 cm2
896 cm2
2508.8 cm2
1. 4 sides each 1/2 (11.2*20)
= 448
224 cm2
448 cm2
896 cm2
2508.8 cm2
1. 4 sides each 1/2 (11.2*20)
= 448
Answer: 448 square centimeters
Step-by-step explanation:
The lateral surface area of a square pyramid is given by :-
[tex]L=\dfrac{1}{2}Pl[/tex], where P is the perimeter of the base and l is the slant height.
Given: The slant height of the pyramid = 20 cm
Side length = 11.2 cm
The perimeter of the square pyramid =[tex]4(side)=4(11.2)=44.8\ cm[/tex]
Now, the lateral surface area of a square pyramid will be :-
[tex]L=\dfrac{1}{2}(44.8)(20)\\\\\Rightarrow\ L=448\ cm^2[/tex]
