Each side of the square is 7 cm (I found the square root of 49).
Then multiply this by 4 (or add by four) to get the perimeter.

If a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
<h3>Define the term average of the number?</h3>
- An averaging is a single number calculated as the average of a set of numbers,.
- Typically calculated as the sum of a numbers divided by the total number of numbers in the set (the arithmetic mean).
You're planning to purchase a sofa from a furniture store that is having a sale on them.
Let x represent the sofa's price.
Advertised sofa's cost = $200
Expensive sofa's cost = $375
The advertisers are aware that when customers arrive at the store, one out of three switch to an expensive sofa that the one shown in the sale advertisement.
Average cost = 375 x 1/4 + 200 x 3/4
E(x) = 375 x 1/4 + 200 x 3/4
E(x) = 93.75 + 150
E(x) = 243.75
Thus, if a advertised sofa is $200 but the more costly sofa is $375, the average cost of such a sofa will be $200 is $243.75.
