Answer:
50.4
Step-by-step explanation:
A scale of 1:40 can be read as "one cm on the model corresponds to 40 cm in the original object". or
"one inch on the model corresponds to 40 inches
this means that the 2 inches correspond to 2 times 40, that is 80 inches and 1.5 corresponds to 1.5*40=60 inches
which means that the original painting has dimensions of 80 by 60 inches.
b) Area = 80 cm * 60 cm = 4,800 cm²
c) 80 cm * 1 inch / 2.54 cm = 31.50 inches ;
60 cm * 1 inch/2.54 cm = 23.60 inches
d) Area = 31.50 in * 23.60 in = 743.40 inches²

Step-by-step explanation:
To find the correct algebraic expression for each table.
For table a)
The values of T is 2 more than the values of n
So, T ⇒ n+2
For table b)
The values of T is 3 less than the values of n
So, T ⇒ n-3
For table c)
The values of T is thrice of the values of n
So, T ⇒ 3n
For table d)
The values of T is 2 more than from the thrice of the values of n
So, T ⇒ 3n+2
For table e)
The values of T is square of the values of n
So, T ⇒ n²
For table f)
The values of T is 1 less than from the twice of the values of n
So, T ⇒ 2n-1
