A rectangle has an area of 102 cm2. The length of the rectangle is 17 cm.

1 answer:

6 0

The area formula is length times width, and since the length is 17 cm in this case, 17 times width = 102, so we must divide 102 divided by 17, and you will get 6. The perimeter formula is 2 times the length plus 2 times the width, so
2(17) + 2(6), which gives us 46, so the perimiter is 46.

Help! Math Homework.

Alenkinab [10]

To solve problem 1 what you need to do is figure out how many miles the girls have walked so far and then subtract that from the total distance they must complete.

3/4-(3/10+1/4)

Step 1:Change the denominators so that way they are all the same

3/4=15/20
3/10=6/20 15/20-(6/20+5/20)
1/4=5/20

Step 2: Begin solving the problem

6/20+5/20=11/20
15/20-11/20=4/20

Step 3: Simplify your answer

4/20=1/5

Step 4 (is optional): Write your answer in a complete statement

-----------------------
5

64+23+78+82+91 = 338.

338
