Answer:
Step-by-step explanation:
This is simple: we need to only do 2 steps
1) Convert to feet
2) Get the area
1) Converting to feet is just
(ignore the use of this it's just to show the differnt things to multiply

Hello :
93-84 =84-75 = 75-66 = 66-57 = 9 ...( common diference of arithmetic <span>sequence )
Un = U1 + (n-1)d d= 9 and U1 = 57 n = 250
U250 = 57 +249(9) = 2298</span>
