Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6 3/4 inches, and Frame B has a length of 7 1/2 inches. What is the width of frame a and frame b. Without calculating predict which frame has a shorter width explain your reasoning

Frame A: 6 1/3 inches Frame B: 6 inches

Step-by-step explanation:

Area= length*width

So... 45 / 6 3/4= 6 1/3

45 / 7 1/2= 6

For the prediction you can put... since fram B is a longer length it will have a shorter width than frame A

gdp is the best phrase!

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
