Answer:
<h2>
2,376 ft²</h2><h2 />
Step-by-step explanation:
surface area = bh + L(s1 + s2 + s3)
where b = 24 ft.
h = 9 ft.
s1 = 15 ft.
s2 = 15 ft.
s3 = 24 ft.
L = 40 ft.
<u>plugin values into the formula:</u>
A = 24*9 + 40(15 + 15 + 24)
= 216 + 40(54)
= 2,376 ft²
8.8-3.4=5.4
Just subtract 8-3 and 8-4 and you'll get 5.4
Hope it helps!

Answers:
<h2>7. 12</h2><h2>8. -√18</h2><h2>9. √220</h2>
Step-by-step explanation:
To find out which is greater, we must eliminate the radical symbol.
#7
