hitesh covers a distance of 7km 800m in making three rounds of a rectangular stadium. if the breath of the stadium is 320m, then find its length.

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:Answer:

Given,

Distance covered by Hiteh in making 3 rounds = 7 km 800 m

                                                                              = 7800 m

Breadth of the stadium = 320m

Let the length of the stadium be 'ℓ'

Distance covered by Hiteh in 1 round = Perimeter of the stadium

Distance covered by Hiteh in making 3 rounds = 7800 m

Distance covered by Hiteh in 1 round = 7800/3

                                                             = 2600 m

∴ The distance covered by Hiteh in 1 round = 2600m

∴ The perimeter of the stadium = 2600 m

Perimeter of stadium = 2 ( ℓ + b )

2600 = 2 ( ℓ + 320)

ℓ + 320 = 2600/2

ℓ + 320 = 1300

ℓ = 1300 - 320

ℓ = 980 m

∴  The length of the stadium = 980 m
