b=base; a=height; A=area=1/2ba
A=1/2bh
30 sq m=1/2 (12m)(a) Divide each side by 6m
5m=a The height is 5m
Since the garden is a right triangle, the third side is the hypotenuse and:
Find square root of each side.
13m=c
The perimeter of the triangle p=a+b+c=5m+12m+13m=30m
ANSWER: It would take 30 meters of fence to surround the garden.
