Answer:
2:10:12
Step-by-step explanation:
I multiplied all of the numbers by 2
It doesn't matter what number you multiply the numbers by, as long as you multiply all 3 of them.
7/8=0.875
7/20=0.35
7/5=1.4
9 29/40 = 9.725
Ok so for area you multiply the length by the width and for perimeter you just add them.. hope this helps!!
