The area of a rectangle is its length times its height
A = bh
A = 3 x 7.5 = 22.5 cm squared
The area of rectangle is : 15.0
An 8x8 rectangle is either a square, all of whose sides are 8 units long or it can be a rectangles whose opposite sides are 8 units long - but in different measurement units: for example, a rectangle whose sides are 8 centimetres and 8 metres.
A metre is a distance - a square metre is an area. A square metre is the area occupied by a square which is 1 metre long on all sides. It is also the area occupied by any rectangle whose sides, when multiplied together, give a figure of 10,000 square centimetres... so a rectangle with sides of 50 centimetres and 200 centimetres, or a rectangle with sides of 80 centimetres and 125 centimetres.... and so on.
if you change the side length the area will change. It is possible to change them and not change the area. For example make side twice and long and the other half as long. But in general, if you change the lengths of the sides the area of the rectangle changes.

If the area is of a rectangle, it is simply the length times the width. If you have a rectangle with sides of 2 and 50 then the area is 100.

A rectangle is a four-sided figure with two long sides and two short sides. The two long sides are the length of the rectangle. The two short sides are the width of the rectangle.
