Find the area of a triangle two sides of which are 18cm and 10cm and the perimeter is 42cm.​

Answer»

{\bold{\pink{\underline{\green{G}\purple{iv}\orange{en}\red{:-}}}}}

  • \bf\:perimeter=42\:<klux>CM</klux>

  • \bf\:First\:side\:(a)=18\:cm

  • \bf\:second\:side\:(<klux>B</klux>)=10\:cm

\bf\:Third\:side\:(<klux>C</klux>)=perimeter-(a+b)

\bf\:Third\:side=42-(18+10)\:cm

\bf\:Third\:side=42-28\:cm

  • \bf\:Third\:side=<klux>14</klux>\:cm

{\bold{\blue{\underline{\red{To}\:\pink{Fi}\green{nd}\purple{:-}}}}}

  • \bf\green{{Area\:of\:triangle=?}}

{\bold{\pink{\underline{\red{So}\purple{lut}\green{ion}\orange{:-}}}}}

Now we have,

a = 18 cm ,b = 10 cm and c = 14 cm

\bf\:Semi\:perimeter=\dfrac{a+b+c}{2}

\bf\:Semi\:perimeter=\dfrac{18+10+14}{2}

\bf\:Semi\:perimeter=\dfrac{42}{2}

\bf\red{{Semi\:perimeter=21\:cm}}

\bf\boxed\star\pink{\underline{\underline{{Using\:heron's\:formula:-}}}}

\bf\:Area=\sqrt{s(s-a)(s-b)(s-c)}

\bf\:Area=\sqrt{21(21-18)(21-10)(21-14)}

\bf\:Area=\sqrt{21\times\:3\times\:11\times\:7}

\bf\:Area=\sqrt{3\times\:7\times\:3\times\:11\times\:7}

\bf\:Area=3\times\:7\sqrt{11}\:c{m}^{2}

\bf\orange{{Area=21\sqrt{11}\:c{m}^{2}}}

Hence,area of triangle will be 21√11 cm²

What is the unit digit in 7^{68} – 3^{59} ?

Answer»

Answer:

From 6^59, we will only GET 6 as the units digit. From 7^71, we will get 7^(68 + 3), ie 3rd term of the CYCLE, ie 3. So EFFECTIVELY the units digit of the EXPRESSION is the units digit of the number 3*6*3, which is 4. (as the number is 54).

Answer»

ANSWER: It is proved below

Step-by-step EXPLANATION: (i) HCF of 14 and 21 is=7

                                                  LCM of 14 and 21 is 42

      Therefore     42 x7=294 which is ALSO equal to 21 x 14= 294

Hence proved

                                                (ii) HCF of 27 and 90 is 9

                                                     LCM of 27 and 90 = 270

Therefore, 270 x 9=2430 which is also equal to 27 x 90= 2430

Hence, proved

Please answer in Urdu story two friends and bear

Answer»

Answer:

ایک بار دو دوست جنگل سے گزر رہے تھے۔ وہ جانتے تھے کہ جنگل میں ان کے ساتھ کسی بھی وقت خطرناک کوئی بھی واقع ہوسکتا ہے۔ چنانچہ انہوں نے ایک دوسرے سے وعدہ کیا کہ وہ کسی بھی خطرے کی صورت میں متحد رہیں گے۔

اچانک ، انہوں نے دیکھا کہ ایک بڑا ریچھ ان کے قریب آرہا ہے۔ ایک دوست ایک دم قریب کے درخت پر چڑھ گیا۔ لیکن دوسرا چڑھنا نہیں جانتا تھا۔ چنانچہ اس کی عام فہمیت کی وجہ سے ، وہ بے جان ہو کر زمین پر لیٹ گیا ، ایک مردہ آدمی ہونے کا بہانہ کیا۔

ریچھ زمین پر پڑے اس شخص کے قریب آیا۔ یہ اس کے کانوں میں مہک رہی ہے ، اور آہستہ آہستہ وہ جگہ چھوڑ گئی۔ کیوں کہ ریچھ مردہ مخلوقات کو ہاتھ نہیں لگاتا ۔اب درخت پر موجود دوست نیچے آیا اور زمین پر موجود اپنے دوست سے پوچھا ، "دوست ، ریچھ نے تمہارے کانوں میں کیا کہا؟" دوسرے دوست نے جواب دیا ، "ریچھ نے مجھے

جھوٹے دوست پر یقین نہ کرنے کا مشورہ دیا۔"

Once two friends were walking through the forest. They knew that anything dangerous can happen to them at any time in the forest. So they promised each other that they would remain united in any case of danger.

Suddenly, they saw a large bear approaching them. One of the friends at once climbed a nearby tree. But the other one did not know how to climb. So being led by his common SENSE, he LAY down on the ground breathless, PRETENDING to be a dead man.

The bear came near the man LYING on the ground. It smelt in his ears, and slowly left the place. Because the bears do not touch the dead creatures.Now the friend on the tree came down and asked his friend on the ground, “Friend, what did the bear tell you into your ears?” The other friend replied, “The bear ADVISED me not to believe a false friend.”
