Well, isn't that just a happy little question! To find the area of a grid, you simply multiply the length by the width. So, for a grid that is 6 cm by 7 cm, you would multiply 6 by 7 to get an area of 42 square centimeters. Just imagine all the wonderful things you could paint on a canvas that size!
Area of circle is pi. r.r. Here r = diameter/2. r = 6 cm. area = 22/7 x 6 x 6 = 113.14 cm sq.
Since there is no shaded part, the answer must be that its area is 0 square units.
The area of a square is (side)2. Since side = 7 cm, then area = (7 cm)2 = 49 cm2 [square centimeters].
Well, honey, to find the area of a rectangle, you just multiply the length by the width. So for a rectangle that's 7 cm long and 3 cm wide, the area would be 21 square centimeters. It's as simple as that, darling.
