Answer:
4√34
Step-by-step explanation:
the question asks for the value of the hypotenuse
Applying the Pythagorean equation
a²+b²=c² where a=12cm, b=20cm and c?
substituting values to equation
12²+20²=c²
144+400=c²
544=c²
√544=c
√16 × √34 =c
4×√34
4√34

4: 2X2
9: 3X3
16: 4X4
25: 5X5
30: (some number not an integer) X (some number not an integer)
36: 6X6
