Area of the square + area of 4 semicircles.
use s² to find the area of the square. s=8
s²=18²=324
use πr²/2
=(3.14 x 324)/2
= <span>508.9
4 semi circles right, 
4 x </span><span>508.9
=</span><span>2035.8
total area = </span><span>2035.8 + 324 
= </span><span>2359.8 ft</span>²<span>
</span>
        
                    
             
        
        
        
Answer: 5
Step-by-step explanation:
 
        
             
        
        
        
Lateral surface area of the prism = 920 in²
Total surface area of the prism  = 1180 in²
Solution:
Length of the prism = 13 in
Width of the prism = 10 in
Height of the prism = 20 in
Lateral surface area of the prism = 2(l + w)h
                                                        = 2(13 + 10) × 20
                                                        = 2(23) × 20
                                                        = 920 in²
Lateral surface area of the prism = 920 in²
Total surface area of the prism  = Lateral area + 2lw
                                                      = 920 + 2 × 13 × 10
                                                      = 920 + 260
Total surface area of the prism  = 1180 in²
Hence Lateral surface area of the prism = 920 in²
Total surface area of the prism  = 1180 in²
 
        
             
        
        
        
The mean is -4 cause u have to add ale the numbers togeter
        
                    
             
        
        
        
We know that:
Area= length*width
Plug in the stuff you know.
35= length(tall)*5
Divide both sides by 5.
7= length
The photo is 7 inches tall.
I hope this helps!
