Answer:
- 4 new classrooms can be built on the newly acquired plot.
- The number of classrooms on the first floor of the school's land = 8
- The amount of extra space on the new land needed to add just 2 more rooms and a soccer field 3/4 of the original land = 375 m²
Explanation:
The current rectangular plot for the school has dimensions 50 m length and 12 m width.
The current school plot has an area of (50×12) that is, 600 m².
The newly acquired rectangular plot, is said to be (1/4) of the current plot.
Area of the newly acquired rectangular plot
= (1/4) × 600 = 150 m²
Each classroom on the current school's plot occupies (1/16) of the the current rectangular plot, area of a classroom on the current plot.
= (1/16) × 600 = 37.5 m²
So, how many classrooms can be obtained from the newly acquired rectangular plot?
Area of the newly acquired rectangular plot = 150 m²
Area of one classroom = 37.5 m²
Number of classrooms obtainable from the newly acquired rectangular plot = (150/37.5)
= 4 classrooms
b) The schoolyard is equal to 3/5 of the land. How many classrooms on the first floor does the school have?
Total area of school land now = 600 m² + 150 m² = 750 m²
Schoolyard occupies (3/5) of the space.
Then, the classrooms on the first floor will occupy (2/5) of the space.
Area occupied by classrooms = (2/5) × 750
= 300 m²
Recall, each classroom occupies 37.5 m² of space,
Hence, the number of classrooms on the first floor = (300/37.5) = 8 classrooms to the nearest whole number.
c) If you wanted to add just 2 more rooms and a soccer field 3/4 of the original land, so much more space would be needed in the new field?
2 more classrooms will occupy = 2 × 37.5 = 75 m²
(3/4) of the original land = (3/4) × 600 = 450 m²
Total new space required = 75 + 450 = 525 m²
The newly acquired rectangular plot has an area of 150 m², So, to achieve those two projects (add just 2 more rooms and a soccer field 3/4 of the original land) that would require 525 m².
The amount of extra space that will be required = 525 - 150 = 375 m²
Hope this Helps!!!
