A garden is 24m long and 14m wide there is a path 1m wide outside the garden along its sides if the path is to be constructed with Square marble tiles 20 multiply by 20cm find the number of tiles required to cover the path
Answers
Answer:
2000 tiles
Step-by-step explanation:
Length of the garden = 24m = 2400 cm
Width of the Garden = 14m = 1400 cm
Width of the path OUTSIDE the garden = 1m = 100cm
Side of 1 marble tile = 20cm
Area of the garden = lb = 2400 * 1400 = 3360000cm²
Total area including the path = (24+2)*(14+2)m = 26*16m = 2600*1600 cm = 4160000cm²
Area of the path = 4160000 cm² - 3360000 cm² = 8,00,000 cm²
Area of 1 tile = S*S = 20*20 = 400cm²
Total tiles needed = 8,00,000 / 400 = 2000 tiles
Answer:
Correct option is C)
Step-by-step explanation:
Area of rectangle =length×breadth
Area of rectangle ABCD=24×14
=336

m
Area of rectangle EFGH=26×16
=416

m
Area of path =416−336
=80

m
Let n tiles are used to cover the path then,
80=n×

80×100
n=2000
hence,
2000 tiles are used.
So option C is correct.
