Question

The 2nd one pls guys idk how to do this

Answer 1

Answer:

answer for the given problem is given

Answer 2

Given :

• The sides of wall are 122 m , 22 m , 120 m .

To Find :

• Rent paid by the company if the company hired one of its wall for 3 months .

Solution :

• a = 122 m
• b = 22 m
• c = 120 m

$\longmapsto\tt{s=\dfrac{a+b+c}{2}}$

$\longmapsto\tt{s=\dfrac{122+22+120}{2}}$

$\longmapsto\tt{s=\cancel\dfrac{264}{2}}$

$\longmapsto\tt\bf{s=132\:m}$

$\longmapsto\tt{Area=\sqrt{s(s-a)(s-b)(s-c)}}$

$\longmapsto\tt{\sqrt{132(132-122)(132-22)(132-120)}}$

$\longmapsto\tt{\sqrt{132\times{10}\times{110}\times{12}}}$

$\longmapsto\tt{\sqrt{2\times{2}\times{3}\times{11}\times{2}\times{5}\times{2}\times{5}\times{11}\times{2}\times{2}\times{3}}}$

$\longmapsto\tt{2\times{3}\times{11}\times{2}\times{5}\times{2}}$

$\longmapsto\tt\bf{1320\:{m}^{2}}$

So , The Area of Flyover is 1320 m² ..

Now ,

$\longmapsto\tt{For\:1\:{m}^{2}=Rs.5000}$

For 1320 m² :

$\longmapsto\tt{1320\times{5000}}$

$\longmapsto\tt\bf{Rs.66,00,000}$

As the company hired one of its wall for 3 months . So ,

$\longmapsto\tt{\dfrac{6600000}{12}\times{3}}$

$\longmapsto\tt\bf{Rs.16,50,000}$
