Totally confused in this one! Thanks a lot if you could help.
Q.1. The diameter of the circles is 4 cm. Calculate the area that is purple.
 

Hello my brother. Here is the answer
First you have to calculate the area of the square so, Length of square = Diameter of two circles = Breadth
Area = 8 * 8
         = 64 cm^2
Area of 1st circle = πr^2
                            = 22/7 * 2 * 2 
                            = 12.57cm^2
Area of 4 circles = 12.57 * 4
                            = 50.28cm^2
Area of purple part = (64 - 50.28)cm^2
                               = 13.72cm^2 Ans
IT IS RIGHT OR NOT TELL ME BY SMILIE

Have you seen the ANSWER!

Hello Suyusha
Diameter of 1 circle is 4 cm and there are two circles in a row or column which means that
diameter of 2 circles= side of square
4cm+4cm=8cm
Now u can find the area of square
And
(area of 1 circle *4)because 4 circles are there.
Then subtract the area of 4 circles from the area of square.
I hope u know how to find the area of square and circle.

It is maths so I will not give u the answer u should try I will only tell u the way to do it

13.72cm2

your solution

Sorry here is little mistake in my answer
