Answer:
28) 120 x 20y
30) 3w x 36
Step-by-step explanation:
28) 20 x (6 x y)
20 x 6 = 120
y x 20 = 20 y
120 x 20y
30) (w x 12) x 3
3 x w = 3w
12 x 3 = 36
3w x 36
Answer:
50
Step-by-step explanation:
For a triangle to be right angled the largest side squared must equal the sum of the squares on the other 2 sides ( Pythagoras theorem)
