First we will find the area of the rectangle....
10*7 = 70cm square.
Now we will find the area of semi circle.....
QR = 7cm each then
the radius will be 7 cm.
area of it will be = 22cm square.
the other will also be 22 cm square.
then the total will be 44 cm square.
Then the remaining area will be .....
70 - 44
= 26 cm square.
10*7 = 70cm square.
Now we will find the area of semi circle.....
QR = 7cm each then
the radius will be 7 cm.
area of it will be = 22cm square.
the other will also be 22 cm square.
then the total will be 44 cm square.
Then the remaining area will be .....
70 - 44
= 26 cm square.
