To find the total area of the octagon you can find the area of the rectangle that is created by the entire figure and subtract the areas of the four congruent right triangles.

(10 cm x 6 cm) - [4(1/2 x 2 x 2)]
60 cm² -8 cm² = 52 cm²

The total area of the octagon is 52 cm².

Answer:

\text{Total area of octagon is }52 cm^2

Step-by-step explanation:

we have to find total area of octagon formed by removing four congruent right triangles from a rectangle.

First we have to find the the area of rectangle whose length and breadth are

Length=2+6+2=10 cm

Breadth=2+2+2=6 cm

Area=Length\times breadth=10\times 6=60 cm^2

Area of 4 congruent right triangles are

=4(\frac{1}{2}\times 2\times 2)=4\times 2=8 cm^2

Area of octagon=area of rectangle-area of 4 triangles

=60-8=52 cm^2[/tex]

\text{Hence, total area of octagon is }52 cm^2

If you draw two cards from the deck at the same time, what is the probability that they will both be hearts?
koban [17]

Answer:

The probability is 1/17.

Step-by-step explanation:

The total number of ways in which 2 cards can be selected from a pack of 52 cards is \binom{52}{2}

The total number of combinations of 2 cards with hearts equals \binom{13}{2}

Thus the probability of the event that both the cards have hearts becomes

P(E)=\frac{\binom{13}{2}}{\binom{52}{2}}=\frac{1}{17}
