Answer: 8/15 + 2/5 = 0.93etc or 14/15
Step-by-step explanation:
Area=length times width
area=10
length=2+√2
width=w
10=(2+√2)(w)
divide both sides by (2+√2)

if we were to rationalize the dnomenator
multiply by



the width is 10-5√2 m
27 in the first group, 36 in the second. Here's the work: Divide 63 by 7 (3 parts plus 4 parts) equals 9. Multiply 9 by 3 for the first group and you get 27, multiply 9 by 4 for the second group to get 36.
