Question

Kanchan runs around a square park of side 90m and Vinita runs around a rectangular park whose length is 120m and breadth is 80m. Who covers the longer distance and by how much?
​

Answer 1

Answer:

Vinita by 40 m

Step-by-step explanation:

(i) Square park:

Given side = 90 m.

∴The Perimeter of a square park = 4 * S

                                               = 360 m.

(ii) Rectangular Park:

Given dimensions are:

Length = 120 m.

Breadth = 80 m.

∴ Perimeter of a rectangular field = 2(l + b)

                                                      = 2(120 + 80)

                                                      = 400 m.

Therefore, Vinita Covers longer distance by 40 m.

Hope it helps!

Answer 2

Answer:

Vinita covers a longer distance by 40 m

Step-by-step explanation:

Kanchan runs arround a park with the side 90 m hence total distance traveled by her is 90*4 = 360

whereas,

Vinita runs arround a rectangular park whose length is 120m and breadth is 80m hence total distance travelled by her is 2*(120+80) = 400

we all know that 400>360 hence Vinita covers a longer distance by 400-360 = 40m
