Answer:
~15.31 or 8(✓2)+4 units
Step-by-step explanation:
a²+b²=c²
16+16=c²
c = ✓32 = 4✓2
2(4✓2) + 4(1) = 8✓2 + 4 ≈ 15.31
For this case you can solve the problem by applying a simple rule of three in which we have
520 ---> 100%
800 ---> x
Clearing x we have
x = (800/520) * 100 = 154%
the percentage increase in cost was
154-100 = 54%
answer
the percentage increase in cost was 54%
