In this page quadratic equation practical solution8 we are going to see solution of practice question of the worksheet quadratic equation practical application.

Question 8:

A chess board contains 64 equal squares and the area of each square is 6.25 cm2. A border around the board is 2 cm wide. Find the length of the side of chess board.

Solution:

Let x be the side length of the square board

Area of one square in the chess board = 6.25 cm²

Area of 64 squares = 64 x 62.5

(x – 4)² = 400

(x – 4)  = 400

(x – 4)  = √20 x 20

x – 4 = 20

x = 20 + 4

x = 24 cm

Therefore side length of square shaped chess board is 24 cm Quote on Mathematics

“Mathematics, without this we can do nothing in our life. Each and everything around us is math.

Math is not only solving problems and finding solutions and it is also doing many things in our day to day life.  They are:

It divides sorrow and multiplies forgiveness and love.

Some people would not be able accept that the subject Math is easy to understand. That is because; they are unable to realize how the life is complicated. The problems in the subject Math are easier to solve than the problems in our real life. When we people are able to solve all the problems in the complicated life, why can we not solve the simple math problems?

Many people think that the subject math is always complicated and it exists to make things from simple to complicate. But the real existence of the subject math is to make things from complicate to simple.”
