Answer:
The width of the walkway is 4 feet.
Step-by-step explanation:
The garden and a walkway around its perimeter have an area of 460 square feet.
The length of the garden = 15 feet
The width of the garden = 12 feet
Assuming that walkway is of uniform width, we can solve the following equation.
Expanding this we get;
We will solve this using quadratic equation formula:
Here a = 4 , b = 54 , c = -280
We get the roots as x = 4 and x =
Neglecting the negative value, we will take x = 4 feet.
Hence, the width of the walkway is 4 feet.
4. You're right that the leg labeled 
occurs in a 1-to-2 ratio with the hypotenuse, but more to the point, it also occurs with the leg of length 10 in a 1-to-
ratio. In other words,
and so
5. In this kind of triangle, the legs form a 1-to-
ratio with the hypotenuse, so it follows that 
.
6. You have and 
mismatched. The larger leg in this kind of triangle has the scaling factor. So in fact, 
, which makes the larger leg 
, and the hypotenuse would be 
.
and so
