Question

A square serving platter has an area of 124 in. 2. Which is the best estimate of the side length of the platter?

Answer 1

Answer:

The correct answer is 11.1.

Step-by-step explanation:

Given:

Area of square platter $124in^{2}$.

If side length of square platter is $x$.

Then, $area=a^{2}$.

As per question, $area=124inch^{2}$.

So, $a^{2}=124$.

Taking square both the sides, $\sqrt{a^{2} }=\sqrt{124}$= $a=11.13$.

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
