do questions number 12
Answers
(i)
Given Dimensions are:
Length of rectangular park = 80 m.
Breath of rectangular park = 55 m.
We know that Area of rectangular park = length * breadth
= 80 * 55
= 4400 m^2.
We know that Perimeter of rectangular park = 2(length + breadth)
= 2(80 + 55)
= 2(135)
= 270 m.
So, Distance covered by Pinky = 270 * 8
= 2160 m.
(ii)
Given Dimensions are:
Side = 75 m.
We know that Perimeter of a square = 4 times the length of a side
= 4 * 75
= 300 m.
So, Distance covered by Pankaj = 7 * 300
= 2100 m.
∴ Difference in distance covered = 2160 - 2100
= 60 m.
Therefore, Pinky covers more distance by 60 m.
Hope it helps!
