Question

the school ground is a large square the length of its side is 400 m what is the perimeter of the school ground a.160,000mb.160,000sq.mc.1,600md.1,600sq.m​

Answer 1

Given,

Side of the square ground = 400m

To Find,

The perimeter of the square ground.

Solution,

The formula for calculating the perimeter of the square is

The perimeter of the square = 4*s, where s is the side of the square

In this case, the side of the square ground is = 400 m

So,

The perimeter of the square ground = 4*400

The perimeter of the square ground = 1600 sq. m

Hence, the perimeter of the square ground is 1600 sq. m.

Answer 2

We need to recall the following formula for the perimeter of the square.

The perimeter of the square $=4*$ length of the side  

This problem is about the perimeter of the square.

Given:

Length of the side of a school ground $=400$ m

Using the formula of the perimeter, we get

The perimeter of a ground $=4*400$ m

                                             $=1600$ m

Hence, the correct option is (c) $1600$ m.
