Answer 1

Answer:

• The required distance covered by Rahul = 1840 metres

Given:

• Rahul like to run along the boundary of a society park. His Park is 100m long and 15m wide one day if he took 8 round of the park.

Need to find:

• The required distance covered by Rahul = ?

Solution:

• Distance covered by Rahul = 8 × Perimeter

➜ Distance covered by Rahul = 8 × 2 × (L + B)

➜ Distance covered by Rahul = 8 × 2 × (100 + 15)

➜ Distance covered by Rahul = 16 × 115

➜ Distance covered by Rahul = 1840

Therefore:

• The required distance covered by Rahul is 1840 metres.

Answer 2

Answer:

_____________________

★ Concept :-

• Here the concept of Perimeter of Rectangle has been used. According to this,

• Perimeter of Rectangle = 2(Length + Breadth)

It should be noted that both Length and Breadth should be in same units.

_____________________

Given : -

• L = 100 m

• B = 15 m

• Total number = 8

Then, distance covered by Rahul,

➠ Distance covered = 8 × Perimeter

➠ Distance covered = 8 × 2(L + B)

By applying the values, we get,

➠ Distance covered = 8 × 2(100 + 15)

➠ Distance covered = 8 × 2(115)

➠ Distance covered = 8 × 230

➠ Distance covered = 1840

★ Hence total distance covered by Rahul

= 1840 m

★ More to know :-

• • Perimeter of Square = 4 × side

• • Perimeter of Circle = 2πr

• where, r is the radius.

• • Area of Rectangle = Length × Breadth

• • Area of Square = (Side)²

• • Area of Circle = 2πr²

• where, r is the radius.
