Asquare serving platter has an area of 124 in. 2. which is the best estimate of the side length of the platter?
a. 31 inches
b. 11.6
c. 11.8
d.11.1
( give an explanation.)

The correct answer is 11.1.

Step-by-step explanation:

Given:

Area of square platter .

If side length of square platter is .

Then, .

As per question, .

So, .

Taking square both the sides, = .

Since the decimal is given in the hundredth position, we can estimate the value to the nearest tenth of a decimal.

Here, the hundredth place has the digit 3.

As 3 is less than 5, we don't add any number to the neighboring digit 1.

So, 3 becomes 0  and the number 11.13 becomes 11.10 and hence 11.1.

Therefore, the correct answer is 11.1

.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

answer: 12   they all have at least 28 days
