Question

The area of a square poster is 31 in squared. Find the length of one side of the poster to the nearest tenth of an inch.

Answer 1

Since, area of square poster = 31 square inches.

We have to determine the length of one side of the poster to the nearest tenth of an inch.

Area of square with side 's' = $s \times s$

So, $31 = s \times s$

$31 = s^2$

$s = \sqrt 31$

s = 5.56

Now, rounding to the nearest tenth, we get the side of the square poster as 5.6 inches.

Therefore, the length of one side of the poster is 5.6 inches.
