When they were younger, Mrs. Corlett's sons shared a trampoline. To separate their play space, she decided to paint a line from one side to the other, across the center of the mat. The safety net that ran around the outside edge of the circular trampoline measured 66 yards.

a. What was the length, in yards, of the painted line rounded to the nearest whole number?

b. What is the area of the mat?

just sum

10 + 10 = 20

fabric (square meters)                   cloaks

7                                                           21

4/3                                                         4

step-by-step explanation:

we are told that harry needs 2 square meters of fabric for every 6 wizard cloaks he makes.

1. first of all we will find how many cloaks can be made from 1 square meter of fabric by dividing 6 by 2.

we can see that 3 cloaks can be made from 1 square meter of fabric. now we will multiply 3 by 7 to find number of cloaks made from 7 square meters of fabric.

therefore, harry will make 21 cloaks from 7 square meters of fabric.

2. let us find how many square meters of fabric will be needed to make 4 cloaks.

first of all we will find fabric needed for 1 cloak by dividing 2 by 6.

we can see that fabric needed for 1 cloak is   square meter. now we will multiply   by 4 to find fabric needed for 4 cloaks.
