Step-by-step explanation:
Given: Side of the square field measure 85m, length of the rectangular field is 130m and the breadth is 72m.
To find: Whether Pinky or Bob ran more distance and the difference.
Answer:
Since it's given that they ran around the field, we will have to calculate the perimeter.
Perimeter of the Square field:
Formula: 4 x Side.
Substituting the value in the formula,
Perimeter = 4 x 85
Perimeter = 340m
Therefore, Pinky ran a distance of 340m.
Perimeter of the Rectangular field:
Formula: 2(Length + Breadth)
Substituting the values in the formula,
Perimeter = 2(130+72)
Perimeter = 2 x 202
Perimeter = 404m
Therefore, Bob ran a distance of 404m.
Now in comparison, Bob ran more distance.
By how much ⇒ The difference.
404- 340 = 64m.
Therefore, Bob ran more distance than Pinky by 64m.
Answer:
BOB. 64CM
Step-by-step explanation:
Distance covered by Pinky= 85cm × 4
= 340 cm
Distance covered by Bod= 2×(130cm + 72cm)
= 2 × 202 cm
= 404 cm
Bob covers more distance then Pinky
by (404cm - 340cm) = 64cm
