The outermost square tile has side length,

The area of a square is given by;

We substitite the given expression for the side length into the formula to obtain,


We expand using the distributive property to obtain;

This gives us:


The last choice is correct.
We know that the deck of cards contain half red and half black cards or you can say we have 26 red cards and 26 black cards.
we have to find probability of red cards from a deck of cards
so,
probability (selecting red card) =

=

Answer:
25.5 seconds
Step-by-step explanation:
Given that the stopwatch records times to the nearest thousandth of a second, it means that the time recorded will be given at 3 decimal places.
To get the time in the nearest tenth of a second, we would first convert to the nearest hundredth of a second, at this, the reading of 25.453 seconds will be
= 25.45 seconds
Since the number at the hundredth position is 5 (or more), we would add 1 to the number at the tenth position to round it to the nearest tenth. Hence the reading to the nearest tenth
= 25.5 seconds
