Here's something I learned, if that's a go math text book the answers are always in the last couple pages of the book
Answer:
11.6km/h
Step-by-step explanation:
multiply 30 min by 2 to get to an hour
multiply 5.8 by 2 to get to km per hour
Triangle
1+1+5=7
7×4=28
28÷2=12
rectangle
12×5=60
whole shape
60+12=72in squared
P=2l+2w
100=2l+2w
divide both sides by 2
50=l+w
So what two numbers that have a sum of 50 have the largest product?
25*25=625 which makes for a large area, the largest
answer=l=25 w=25
