Question

To make a square 4 match sticks are needed and 2*4 match sticks are needed to make 2 squares. How many match sticks are needed to make n number of squares? Write the constant and the variable of the number?

Answer 1

Concept:

Multiplication produces a product, or an expression that indicates factors to be multiplied.

Given:

4 match sticks are needed to one square

2*4=8 match sticks are needed to make 2 squares

To find:

How many match sticks are needed to make n number of squares?

Solution:

We are given that to make a square we need 4 match sticks and to make two squares, we need 8 match sticks.

In other words, we can write it as,

$1 square= 4\\2 squares= 2*4\\=8$

Now, we have to find the number of match sticks required to make n number of squares.

So, we know that a square has 4 sides, so n number of squares will have 4n number of sides.

Hence, we will need 4n $(4*n)$ numbers of match sticks to make n numbers of squares.
