Answer:
65, 72, 97
Step-by-step explanation:
Here,
According to figure,
longest side is 97. So it the length of hypoteneous(h) and the shortest side is 65 so it is the length of perpendicular(p) and last one, 72 is the lenght of base(b) of triangle.
According to Pythagorus theorem,

which is true.
If you test the same theorem in other options.The reasult will unsatisfied.
Perimeter is the distance around a shape. The way you find it is by adding the lengths of every side.
In this case, it is 3+4+5=12 cm
If you would like to find the area of the base of the fountain, you can calculate this using the following steps:
1 2/3 ft * 2 2/3 ft = 5/3 * 8/3 = 40/9 = 4 4/9 square feet
The area of the base of the fountain is 4 4/9 square feet.
