Justin wanted to place pots of carnations at equal distance apart from each other along the perimeter of his square garden. He placed a flower pot at each corner and an equal number of flower pots along each side of the square garden. He had 79 pots of flowers to use.
- What was the maximum number of flower pots Mr Ong could use to place along the perimeter of the square garden?
- How many flower pots would there be along each side of the square garden including the flower pots at the 2 corners?
(a)
Number of pots left after placing one on each corner of the garden
= 79 - 4
= 75
Number of pots possible to be placed on each side excluding those placed at the corners
= 75 ÷ 4
= 18 r 3
Maximum number of flower pots used
= 18 x 4 + 4
= 76
(b)
Number of flower pots on each side
= 18 + 2
= 20
Answer(s): (a) 76; (b) 20
