You originally draw a design for an art contest on a 4 in. x 5 in. card. The second phase of the contest requires the drawing to
be transferred to an 8.5 in x 11 in. standard sheet of paper and utilize as much of the space on the paper as possible. You determine that the largest size one of the dimensions of your drawing can be is 10.5 in. What is the length of the other dimension if the two drawings are similar? Type your exact answer in the blank without the units, and round to the nearest tenths.
By using ratio and proportion the problem can be solve. First
assume that 10.5 in is the length of the new drawing, and let w be the width
4 / 5 = w / 10.5
W = 10.5 ( 4 / 5)
W = 8.4 in
<span>So the new dimensions are 8.4 in x 10.5 in </span>
