Answer:
i) width = 3.75
length = 4.5
ii) 6.75m^2
iii) 78.75m^2
Step-by-step explanation:
11)
i) Bedroom 1
actual width = 2.5 × 1.5
= 3.75 m
actual length = 3 × 1.5
= 4.5m
ii) Kitchen
actual width = 1.5 × 1.5
= 2.25 m
actual length = 2 × 1.5
= 3 m
actual area = 2.25× 3
= 6 .75 m^2
iii) Apartment
actual width = 5 × 1.5
= 7.5 m
actual length = 7 × 1.5
= 10. 5 m
actual area = 7.5 * 10.5
= 78.75 m ^2

Answer:
2.12 ft above ground level
Step-by-step explanation:
Volume of the cylindrical tank is 36*π
Tank is filled to half its capacity, that means tank is filled 18*π, and level of water is 4 feet, then the height of the cylinder is 8 feet
With the above information we can calculate the radius of the base of the cylinder, according to
V = 36*π = π*r²*h ⇒ 36 = r²*h ⇒ 36/8 = r² ⇒ r = 2.12 ft
Then the radius of the base is 2.12 ft
When the cylindrical tank is place on its side, the level of water inside have to be 2.12 ft above ground level. That is the level of half its capacity
