Answer:
B
Step-by-step explanation:
Formula: 4*((15*7)/2) + 15^2
This is the area of the four triangles combined (210 cm^2) plus the area of the square (225 cm^2)
The LCM of 15 and 25 is 75
The LCM is the smallest number that you can get from multiplying both numbers.
multiples of 15: 15, 30, 45, 60, 75...
multiples of 25: 25, 50, 75....
as you can see, 75 is the first number to pop up in both.
