Answer:
The length is 10 yards and the width is 20 yards of the playground.
Step-by-step explanation:
Given,
Area of the rectangular playground = 200 yards.
Solution,
Let the length of the playground be x.
Then the width of the playground is 2x.
Now, According to the formula of area of rectangle;
On substituting the values, we get;
So the length of the playground is 10 yards.
Since the width is twice of the length.
So width =
Hence the length is 10 yards and the width is 20 yards of the playground.

Answer:
22 rows and 22 flags are needed
Step-by-step explanation:
Total number of vendors = 88
Existing number of rows and flags= 4
Number of rows and flags needed= 88/4 =22
Answer:
4rows and 16flags
Step-by-step explanation:
Since there were 88 vendors at the craft fair and 4flags on each rows. To set up equal number of vendors on each row, we will use the expression;
Number of vendors per row = Total number of vendors/total number of flags per row = 88/4 = 22 vendors
If there are 22 vendors in a rows and there are 88vendors in total, the total of rows will be;
Total number of vendors/number of vendors per row
= 88/22
= 4 rows
If there are four rows in total and 4flags in each row, the total of flags needed will be;
Total number of row × total flag per row
= 4×4
= 16flags
This shows that there are 4rows and 16flags were needed.
