Hello!
So, we know that the length of the rectangular basketball court is 84 ft, and the width is 50 ft. 
The formula for perimeter of a rectangle is: 
P = 2l + 2w
This means that we need to multiply the length by two and the width by two as well. 
Substitute: 
P = 2(84) + 2(50)
P = 168 + 100 
P = 268 ft 
ANSWER: 
The perimeter of the basketball court is 268 feet long.
        
             
        
        
        
Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Final answer: D
        
                    
             
        
        
        
240,000 = 24 x 10,000 but 10,000 = 10 x 10 x 10 x 10 = 10⁴, then:
240,000 = 24 x 10⁴
        
             
        
        
        
Answer:
<h2>
67.7</h2><h2 />
Step-by-step explanation:
perimeter = semicircle (x2) + parallelogram side (x2)
                 = 1/2 π 12 (x2) + 15 (x2)
                = 37.7 + 30
                = 67.7
