Question

a boy runs only along all the sides of a rectangular field whose length is twice its breadth if the breadth vthe field is 25m find the distance covered by the boy

....​

Answer 1

Answer:

Explanation:

Distance covered is the perimeter of the field.

Breadth is 25 m and the length is double the breadth. Then length is 50m.

Perimeter =2(l+b)

2(50+25)=2*75

=150m

hope it helps you :)

good morning bro

Answer 2

Answer:

Given :

the breadth of the field is 25 meters

the length is twice its breadth.

To find :

the distance covered by the boy

Solution :

⇒ It is said that the length is twice the breadth. So, we have to multiply it by 2.

Breadth = 25 m

Length = 2 x 25 m

= 50 m

Now,

⇒ To find how much distance is covered by the boy, we have to calculate the Perimeter.

Perimeter = (2 x l) + (2 x b)

= (2 x 50) + (2 x 25)

= 100 + 50

= 150 m

Therefore, the boy covered a distance of 150 m.
