Question

a rectangular field measures 400m by 550m what is the perimeter of the field in kilometers

Answer 1

Answer:

1900m

Step-by-step explanation:

perimeter of rectangle = 2(length+breadth)

= 2(400+550)

=2(950)

= 2*950

=1900m

Answer 2

Question :

A rectangular field measures 400m by 550m. What is the perimeter of the field in kilometers?

------------

Given :

• Length = 400 m
• Breadth = 550 m

To find :

• the perimeter

Steps :

• Here, we have to find the perimeter of the rectangular field.
• Then, we have to convert them into kilometers by dividing them by 1000.

Solution :

⇒ Let's find the Perimeter of the field.

Perimeter of field = 2(l + b)

                             = 2(400 + 550)

                             = 2(950)

                             = 2 × 950

                             = 1900

Therefore, the perimeter is 1900 m.

⇒ Now, let's convert them from meters to kilometers.

[1 kilometer = 1000 m]

1900 m = 1900/1000

            = 1.9 km

• Therefore, the perimeter in kilometers is 1.9 km.
