The triangular side walls of a flyover have been used for advertisements. The sides of the walls are 122m, 22m and 120m. The advertisements yield an earning of rupees 5000 per m^2 per year. A company hired one of its walls for 3 months. How much rent did it pay?

1499750 rupees

Step-by-step explanation:

Let's find the area of the triangle first

S= (122+20+120)/2

S = 131

Area = √(131(131-122)(131-20)(131-120))

Area=√( 131(9)(111)(11))

Area= √(1439559)

Area= 1199.8 m²

5000 rupees per m² per year

So in a year it will earn

5000 = 1 m²

1199.8m² = 5000*1199.8

= 5999000 rupees for the year

In three months it will earn

5999000*(3/12)

= 5999000(0.25)

= 1499750 rupees

unpaid balance is : $149.99-$50 = $99.99 new balance = 149.99+2.62-50 = $102.61 finance charge = 99.99- 0.21/12= $1.75 new balance = 99.99+1.75 = $101.74 average daily balance method average daily balance= 3399.70/30 = $113.32 finance charge = $ 0.21/12ă—113.32 = $1.98 new balance = $149.99-50+1.98 = $101.97
