Question

Ally runs around a square field of side 75 m, Bob
runs around a rectangular field with length 160 m and breadth
105 m. Who covers more distance and by how much?

Answer 1

Question:

Ally runs around a square field of side 75 m, Bobruns around a rectangular field with length 160 m and breadth 105 m. Who Covers more distance and by how much?

Given:

Side of square = 75m

Length of Rectangle = 160m

Breadth of Rectangle = 105m

To find:

Among Ally and bob who covers more distance and by how much?

Solution:

Ally runs around a square field of side 75m, so we need to find the perimeter of the field to find the distance covered by Ally

Perimeter = 4 x Side

⠀⠀⠀⠀⠀⠀ = 4 x 75

⠀⠀⠀⠀⠀⠀ = 300cm

Hence Distance Covered by Ally is 300cm

Bob runs around a rectangular field of length and breadth 160m and 105m respectively, so we need to find the perimeter of the field to find the distance covered by Bob

Perimeter = 2(l + b)

⠀⠀⠀⠀⠀⠀ = 2(160 + 105)

⠀⠀⠀⠀⠀⠀ = 2(265)

⠀⠀⠀⠀⠀⠀ = 530m

Hence Distance Covered by Bob is 530cm

Difference in length = 530 - 300

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀= 230m

Hence Bob covers more distance than ally by 230m

Answer 2

Answer:

here's your answer, grab it

Step-by-step explanation:

GIVEN -

SIDE OF THE SQUARE FIELD AROUND WHICH ALI RUNS = 75M

SIDE OF THE RECTANGULAR FIELD AROUND WHICH BOB RUNS => L = 160 , B =105M

to find who covered more distance, we will have to find out the distances covered by each.

DISTANCE COVERED BY ALI -

(both are running around the field so we will hae to find their perimeter is 2 find the distance covered by each)

perimeter of square = 4a

=75 * 4

= 300m

Though the distance covered by Ali is 300 metres.

DISTANCE COVERED BY BOB -

perimeter of rectangle - 2(l + B)

= 2 ( 160 +105)

= 2 * 265

= 530m

though the distance covered by Bob is 530m

NOW COMPARE BOTH THE RESULTS -

530 > 300

BOB covers more distance than Ali , let's find out by how much.

530 - 300= 230m

So BOB covers more distance than ALI by 230m .
