The width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.
What is a scale factor?
The ratio among comparable dimensions of an object and a model with that object is known as an exponent in algebra. The replica will be larger if the scale factor is a whole number. The duplicate will be lowered if the step size is a fraction.
We have:
A video screen is 16 in. by 12 in. tall.
To find the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall, we can use the scale factor:
Applying the similarity law:
6/12 = 4/x
1/2 = 4/x
x = 4×2
x = 8 in
Thus, the width of the largest complete image possible for a photograph that is 4 in. wide by 6 in. tall is 8 in option (B) 8 in is correct.
