A film projector magnifies a `100cm^(2)` film strip on a screen. If the linear magnification is 4, the area of the magnified film on the screen is

A

`1600 cm^2`

B

`400 cm^2`

C

`800 cm^2`

D

`200 cm^2`

Text Solution

Verified by Experts

The correct Answer is:
A
`A_1 = m^2 A_0`
`therefore A_1 = (4)^2 xx 100`
`therefore A_1 = 1600 cm^2`
