\\ \rm\rightarrowtail s=\dfrac{a+b+c}{2}

\\ \rm\rightarrowtail s=\dfrac{1.8+2.4+3}{2}

\\ \rm\rightarrowtail s=\dfrac{7.2}{2}=3.6cm

Apply heron s formula

Area:-

\\ \rm\rightarrowtail \sqrt{s(s-a)(s-b)(s-c)}

\\ \rm\rightarrowtail \sqrt{3.6(3.6-1.8)(3.6-3)(3.6-2.4)}

\\ \rm\rightarrowtail \sqrt{3.6(1.8)(0.6)(1.2)}

Answer:

<h3>1863 m squared</h3>

Step-by-step explanation:

So, the goal here is to find the area of each block individually then add it all together. In other words, you're gonna look for a way to solve for the missing square in the total large rectangle. Keep in mind 23 + 23 + 23 = 69 (aka the length of the whole rectangle)

So:

12 x 23 = the missing square = 276

31 x 69 = rectangle with the square = 2139

Total area = 2139 - 276 = 1863

Five cards from a standard deck of 52 cards is dealt. find the probability that the card hand contains exactly 2 red cards and 3
Marizza181 [45]
Hello!

We know that there is a 1/2 chance of selecting either color. Let's say that the numerator represents red and the denominator represents black. We have a 1/2 chance of picking a red card overall. In this scenario, we have the event of 2/3. If we multiply these fractions we get 2/6, which is equal to 1/3.

The probability is 1/3.

I hope this helps!
