Question 333575: the flower garden has the shape of a right triangle. 5 ft of a perrineal border forms the hypotenuse of the triangle and one leg is 1 ft longer than the other legs, find the lengths of the legs
Can you please help me thank you

When you are dealing with a right triangle and you are trying to find lenght of the sides, you will most likely end up using the pythagorean theorem which states: where c is the side opposite the right angle, and is called the hypotenuse.
--
Given in your problem: c=5, a=x and b=x+1
so by the pythagorean theorem of a right triangle:
---
(expanding the squared term)
(combining terms)
(putting the quadratic equation in standard form}}}
(divide the whole thing by 2, to simplify the equation)
0=(x+4)*(x-3) (factor the expression on the right)
x=-4, x=3, since we are dealing with lengths, the negative value x= -4 is extraneous and can be trown out
--
so, one side is a=x=3 and the other is b=x+1=4
--
what you have is a special type of right triangle where the sides are in a ratio 3:4:5
