Step-by-step explanation:
The perimeter of a rectangle is given by (l is length, w is width):

Plug in the values:

So, the perimeter of the rectangle is 32ft.
11m
The area of a triangle is bh/2. If we know the height (8m), we can plug it into a=bh/2 for a=8h/2 or a=4h or a/4=h
Since we know the area (44m^2), we can put that in for 44/4=h or h=11 metres.
