Well, honey, to find the perimeter of a rectangle, you add up all the sides. So, for your rectangle with sides of 12m and 8m, you simply add 12 + 12 + 8 + 8 to get a perimeter of 40 meters. Voila!
8m*5m=40 m2 The area of the rectangle is 40m2
36 m
What is the volume of an m and m
Rectangles don't have volume or height.
Area = 12*8 = 96 square m

There cannot be a 12m rectangle. A rectangle is a two dimensional object and so there must be two linear measures to describe it. Either there is measure of another length, for example a 12m x 8m rectangle. In that case the question is redundant. Or the 12m is intended as a measure of area and should actually have been 12 SQUARE metres. However, in that case, there are infinitely many possible solutions.
8m*5m=40 m2 The area of the rectangle is 40m2
The 8m X 8m area in the inner part of the Competition Area of 12m X 12m shall be called the Contest Area and the outer part of the Contest Area shall be called the Alert Area.
The area of rectangle is : 72.0
40m
25.6m2
36 m
Area of rectangle = length * width = 9*8 = 72 metres2
The lengths of the sides of a quadrilateral are not enough to determine its area since the shape is not rigid: it can be flexed.
Perimeter is 36 mArea is 72 square m
