The area of a grid can be calculated by multiplying its length by its width. For a grid that is 7 meters long and 5 meters wide, the area is 7m × 5m = 35 square meters. Therefore, the area of the grid is 35 m².

Let the width of the rectangle be ( w ) cm. Then, the length can be expressed as ( w + 7 ) cm. The area of the rectangle is given by the equation ( w(w + 7) = 60 ). Solving this quadratic equation, we find that the dimensions of the rectangle are a width of 3 cm and a length of 10 cm.
The area of a 12 by 7 grid is 84.
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!

A 7-by-9 grid has an area of 63 square units.
Cylinder volume = height 10 cm > radius 7 cm > base area of the cylinder = 153.9380400 cm2 Volume = base area x height = 1539.380400 cm 2

The area of a square is (side)2. Since side = 7 cm, then area = (7 cm)2 = 49 cm2 [square centimeters].
A triangle with side a: 7, side b: 7, and side c: 7 cm has an area of 21.22 square cm.
7 cm is equivalent to 70 mm because there are 10 millimeters in one centimeter (1 cm = 10 mm).
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.
