Question

Rocky takes 10 rounds of a rectangular park 100m long and 50m wide find the total distance covered by him

Answer 1

in this problem we solve

perimeter of rectangular park = rocky cover one round

perimeter = 2 × ( length + breath)

2 × ( 100 + 50 )

2 × 150 = 300 meter

total distance cover in 10 round is

10 × 300 m = 3000 meter

or 3 km

Answer 2

Heya Friend !!

Length of park = 100 m (given)
Breadth of park = 50 m (given)

Perimeter of rectangular park = 2(l+b)
=> 2(100+50)
=> 2×150
=> 300 m

Distance covered by Rocky in
1 round = 300 m

It is given that Rocky took 10 rounds
So , total distance covered by him
=> 10×300
=> 3000 m

hope this helps :-)
