<h2><u>Direct answer</u> :</h2>
Width of the enlarged photograph = 14 cm
<h2><u>Steps to derive the correct answer</u> :</h2>
Length of a small photograph = 6 cm
Width of a small photograph = 4 cm
Length of the photograph when enlarged = 21 cm
Let the width of the photograph when enlarged be x.
Which means :






Thus, the value of x = 14
Therefore, the width of the enlarged photograph = <u>14 cm</u>
Cross products: a/b = c/d is also equal to ad = bc
so, essentially you’re just drawing two diagonal lines from one side to the other, multiplying those numbers together, and setting them equal
so: 4/6 and 14/21 = (4*21 = 6*14) = (84 = 84)
84 is equal to 84 so these two ratios are equivalent.
