A) 75
The two triangles are similar, ABC is an enlargement of RST by scale factor 2.5. So all lengths are 2.5 times larger than the lengths for RST
This gives us lengths of 30, 32.5 and 12.5
Adding these together gives us 75 for the perimeter
B) 30
We can work out the missing side of RST using Pythagoras’ theorem, it is 12
(12x5)/2 = 30
C) 187.5
We can use the same method as in B and use the formula for the area of a triangle to work out that the area for ABC is 187.5
