Question

length and breadth of a rectangular park is 10 m & 15 m . if a girl take two time round of whole park , then tell what is the total cover distance by girl .​

Answer 1

Solution

Given :-

• Length & breathe of rectangular park = 10 & 15m

Find :-

• Cover distance by girl of whole park

Explanation

We Know ,

$\dag\boxed{\underline{\tt{\red{\: Perimeter_{rectangle}\:=\:2\times (Length+Breadth)}}}}$

So, First Calculate Area of rectangular park

==> perimeter of rectangular park = 2 = (10 + 15)

==> perimeter of rectangular park = 2 ×(25)

==> perimeter of rectangular park = 50 m

__________________________

We can say , if girl take a round of whole park its will be distance of one round .

Since,

If she take whole 2 round of whole park it will be total cover distance = 50 × 2 = 100 m

Hence

• Total cover distance cover by girl will be = 100 m
