Answer 1

Answer:

Step-by-step explanation:

let side of the square track be 'a'

Given: 10 × Perimeter of the park = 4km

=> 10 × 4a = 4000 m

=> 4a = 400 m

=> a = 100m

=> a = 0.1 km

therefore, length of the park is 0.1 km

Answer 2

GIVEN ⤵️

brijendr runs 10 times aroind a square track and cover 4 km

ANSWER ⬇️

We know that,

We know that 1 km=1000 m

4 km=4×1000 km=4000 km

Bajinder runs ten times around a square track cover 4 km

=10×4a=4000 m

⇒40a=4000 m

⇒a=4000/40=100 m

∴ Length of track =4×100 m=400 m.
