Answer:
The answer to your question is Area = 3240 ft² or Area = 360 yd²
Step-by-step explanation:
Data
length = 30 yd
width = 36 ft
Area = ? ft²
Area = ? yd²
Process
1.- Convert the units
1 yd --------------------- 3ft
30 yd ------------------ x
x = (30 x 3)/1
x = 90 ft
1 yd ------------------- 3 ft
x ------------------- 36 ft
x = (36 x 1) / 3
x = 12 yd
2.- Calculate the area of the rectangle in ft²
Area = length x width
-Substitution
Area = 90 x 36
= 3240 ft²
3.- Calculate the area in yd²
Area = 30 x 12
= 360 yd²
The length if the upper portion of the stand is 33. 56 inches
<h3>How to determine the length</h3>
The formula for the finding the length is given thus;
Total height = length of upper portion + length of base
Where
Length of base = 257/16
Total height = 591/2
Length of upper portion = total height - length of base
= 118/2 - 407/16
= 59 - 25. 44
= 33. 56 inches
Thus, the length if the upper portion of the stand is 33. 56 inches
