The ratio of the perimeter of a square to the length of a rectangle is 5:6. The ratio of the length to the width of the rectangle is 3:2.
The perimeter of a rectangle is 60cm.
Find the area of the square.

=225/16cm^2

Step-by-step explanation:

Given

The ratio of the length to the width of the rectangle =3:2.

The perimeter of a rectangle = 60cm.

Solution

Let length=3x

width=2x

Perimeter of rectangle=2(length + width)

2(3x+2x)=60

5x*2=60

10X=60

X=60/10

X=6

SO LENGTH =3×6=18cm

WIDTH=2×6

=12cm

Let perimeter of the square=5x

Length of rectangle=6x

6x = 18

X=18/6

X=3

SO PERIMETER OF SQUARE=5×3

4SIDE=15

Side=15/4

Area of square=15/4×15/4

=225/16cm^2

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.
