The triangular side walls of a flyover have been used for advertisements. The sides of the walls are 122m, 22m and 120m. The adv
DedPeter [7]

Answer:

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

Evaluate the function f(x) = x 2 + 1 for f(2). 1 5 7
Burka [1]
If you get a function like f(2), you have to know that the 2 in the brackets/parentheses pretty much replaces the “x” in the equation. Think about it:

If we have f(x) and f(2), that must mean x=2

So we insert the value of x into the function and we get:

f(2)= 2*2+1=4+1=5

So 5 is the answer

of you would Write a decimal that represents the value of one $1 bill and 5 quarters how would you write that?
Snowcat [4.5K]
Well $1 bill and 5 quarters would be written as 1.25 in decimal form.

This is because 4 quarters equal $1.00. You add another quarter and you get $1.25. Hope this helps!!
