Answer:

24649-17424=7225 UNITS

Step-by-step explanation:

This step implies that Lara was using the Pythagoras theorem to find the missing length of the right triangle.

a²+b²=c², taking a and b to be the  two lengths adjoined by the right angle and c the hypotenuse.

Laura's step represents the step above.

157²=24649

132²=17424

157²-132²=c²

24649-17424=7225
