To solve the problem, I will have to solve the equation for the first shape.
5^2 + 4^2 = 25 + 16 = 41
The second shape seems to be 2.5 times bigger than the first shape.
7x - 5 + 24 = 102.5
+5 +5
7x + 24 = 107.5
-24 -24
7x = 83.5
7 7
x = 11.9285714286
x = 11.9^2
11.9^2 = 141.61
Looking at the angles we know, there's a 4 and a 24 so the second shape is 6 times larger than the first shape. There's also a 5 which means the solution to the problem, 7x - 5, should be 30.
7x - 5 = 30
+5 +5
7x = 35
7 7
x = 5
Answer: The side of 7x - 5 is equal to 5cm.
