You helped organize a birthday party for twenty kids. You filled 150 water balloons and the kids smashed 4/5 of them in ten minutes. How many total balloons are leftover?

30

Step-by-step explanation:

Okay, to find the number of balloons left over, disregard the number of kids and focus only on 150 balloons and that only 4/5 were "smashed." Multiply 150 by 4/5 to find the amount of balloons used, which is 120, and find the difference between 150 and 120, which is 30.

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
