a). Area = (length) (width)
= (60 ft) (√18 ft)
= (60 √18) ft²
= 60 √(9 · 2) ft²
= 60 (3) √2 ft²
= 180 √2 ft² (about 254.6 ft²)
b). Volume = (length) (width) (height)
= (60 ft) (√18 ft) (√10 ft)
= 60 √(180) ft³
= 60 √(4 · 9 · 5) ft³
= 60 (2) (3) √5 ft³
= 360 √5 ft³ (about 805 ft³)
length =88cm
breadth=21cm
when it is rolled it becomes cylinder
having circumference 88cm
2πr=88cm
r=88×7/44
r=14
h=21
total surface area of the cylinder =2πr(r+h).
=2×22/7×14(14+21)
=3080cm²
Answer:
(1.5, -13.5)
Step-by-step explanation:
Midpoint Formula: 
Simply plug in our coordinates into the formula:
x = (17 - 14)/2
x = 3/2
y = (-11 - 16)/2
y = -27/2
Answer: the first one is C
the second one is B
