Jackson rectangular bedroom has an area of 90 square feet .the area of his bedroom is 90 square feet. the area of his bedroom is9 times that of his rectangular closet. if the closet is 2 feet wide what is the length?

the length of the rectangular closet is 2 feet

Step-by-step explanation:

The formula for determining the area of a rectangle is expressed as

Area = Length × width

Jackson's rectangular bedroom has an area of 90 square feet. The area of his bedroom is 9 times that of his rectangular closet. This means that the area of his rectangular closet would be

90/ 9 = 10 square feet

If the closet is 2 feet wide, then the length would be

Area/ width = 10/2 =5 feet

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.
