Question

47. The area of a rectangular field is 3400 m and its length is 68 m. Find
(i) its breadth
(ii) the distance covered by a man in going 5 times around the field.​

Answer 1

Answer :

• The breadth of the rectangular field is 50m
• The distance covered by a man in going 5 times around the field is 1180m

Step-by-step explanation :

To Find,

• The breadth
• The distance covered by a man in going 5 times around the field

Solution,

Given that,

• Area of the field = 3400 m²
• Lenght = 68 m

Therefore,

The breadth of the rectangular field is,

As we know that,

( l × b ) = Area of the rectangle

Where

• l = lenght
• b = breadth

➮ ( 68 × breadth ) = 3400

➮ Breadth = 3400 / 68

➮ Breadth = 50m

Hence, the breadth of the rectangular field is 50m.

Now, the distance covered by a man in going 5 times around the field, So first we need to find out the perimeter of the field

As we know that,

Perimeter = 2( Length + Breadth )

By putting the values,

➮ 2 ( 68 + 50 )

➮ 2 × 118

➮ 236

Therefore, the distance covered by the man

➮ 236 × 5

➮ 1180

Hence, the the distance covered by a man in going 5 times around the field is 1180 m.

Answer 2

Step-by-step explanation:

i) area of rectangular field = 3400

length×breadth=3400

68×b=3400

b=3400/68

b=50
