Answer:
Surface area of the reflective glass is 543234.4 square feet.
Step-by-step explanation:
Given that: height = 311 feet, sides of square base = 619 feet.
To determine the slant height, we have;
=
+ 
= 96721 + 95790.25
= 192511.25
⇒ l = 
= 438.761
The slant height, l is 438.8 feet.
Considering one reflecting surface of the pyramid, its area =
× base × height
area =
× 619 × 438.8
= 135808.6
= 135808.6 square feet
Since the pyramid has four reflective surfaces,
surface area of the reflective glass = 4 × 135808.6
= 543234.4 square feet
Answer:
11/5
Step-by-step explanation:
2x+12+4-12x+6
-10x+22
x=22/10
x= 11/5
22/5+12+4=123/5-6
102/5=123/5-30/5
102/5=97/5
102/5-97/5
5/5

Option A is correct
Answer:
96 sq. cm.
Step-by-step explanation:
A "kite" has 2 diagonals, which are the "width" and "height" of the kite.
Using diagonals, the area of a kite is given by 
Where
A is the area
p,q are the width and height, respectively
From the problem given, p is 12 and q is 16, so the area is:

Thus, the area is 96 sq. cm
