Question

A rectangle is 17 in tall and 19.5 wide if it’s reduced to a height of 3.4 in then how wide will it be

Answer 1

3.9 in

Explanation:

Write and solve an equation of ratios:

3.4 in w

----------- = -----------

17 in 19.5 in

Cross-multiplying results in:

(3.4)(19.5) in² = 17w in

Dividing both sides by 17 in results in:

3.9 in = w

thus, the width of this smaller rectangle will be 3.9 in.
