Divide it by 100.
The perimeter of a rectangle is given by:P = 2l + 2w, where P is the perimeter of the rectangle, l is the length of the rectangle, and w is the width of the rectangle.P = 2(15) + 2(10) = 50 meters.
As the relationship between the length and angle given are unclear a graphic explanation can be found at the link below
Find the width, and multiply the length and the width.
The area of the triangle in square meters is (1/2 the length of the triangle's base, in meters) times (the length of the triangle's height, in meters).
84/5 = 16.8 meters

double the length
You cannot.
57 meters. To find area you multiply base times height, or width times length in this case.

You can't "change" centimeters to meters. But you can describe a length or a distance in terms of either unit. -- If you know the length in centimeters, divide that number by 100 to find the number of meters in the same distance. -- If you know the length in meters, multiply that number by 100 to find the number of centimeters in the same distance.
You need the length AND the height in order to find the area
