PLZ ANSWER ASAP THX<br><br><br> Find area

Elan Coil [88]

Area of triangle , when 3 sides are given , we may use "Heron's formula"

$\bold{heron \: formula \: = \: \sqrt{s(s - a)(s - b)(s - c)square \: units} } \\ \\ where \: \bold{s }= \frac{a + b + c}{2}$

Given :

a=7

b=8

c=10

So , semi peremeter =

$s = \frac{7 + 8 + 10}{2}$

$s = \frac{25}{2}$

$s = 12.5$

$area = \sqrt{12.5(12.5 - 7)(12.5 - 8)(12.5 - 10)}$

$area = \sqrt{12.5(5.5)(4.5)(2.5)}$

$area = \sqrt{68.5 \times 11.25}$

$area = \sqrt{770.625}$

$area \: = 27.7601 {units}^{2}$

jarptica [38.1K]

Answer:

5/14

Step-by-step explanation:

There are 15 tiles in total

5 white| 6 black | 4 blue

event A results in the subject pulling a white tile and not replacing it

5-1= 4

so the first answer should be 4/15

event B results in the subject pulling another tile, a black one and not replacing it.

6-1= 5

given this answer, there is one less tile in the total, since we removed another tile.

So our answer would be-

5/14 or D
