The GCF of 12m, 15m and 30m is 3m.
24am - 9an + 40bm - 15bn = 3a*(8m - 3n) + 5b*(8m - 3n) = (3a + 5b)*(8m - 3n)
m2 + 12m + 20 = ( m + 2)(m + 10)
It is 50%.
The GCF is 8. 8(m + n)
The area of rectangle is : 96.0
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!
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

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
