Answer:
Side of square bed = 1 m
Area of square bed = side * side = 1 m * 1 m = 1 m2
Area of 5 square beds = 1 * 5 = 5 m2
Now, Length of land = 5 m
Breadth of land = 4 m
Area of land = length * breadth
= 5 m * 4 m = 20 m2
Area of remaining part = Area of land – Area of 5 flower beds
= 20 m2 – 5 m2 = 15 m2
11.)
a) Area of region = 100 cm * 144 cm = 14400 cm2
Area of one tile = 5 cm * 12 cm = 60 cm2
Number of tiles = Area of region/Area of one tile
= 14400/60
= 240
Thus, 240 tiles are required.
(b) Area of region = 70 cm * 36 cm = 2520 cm2
Area of one tile = 5 cm * 12 cm = 60 cm2
Number of tiles = Area of region/Area of one tile
= 2520/60
= 42
Thus, 42 tiles are required.
