Consider the enlargement of the rectangle. A smaller rectangle with length of x inches and width of three-fifths inch. A larger rectangle with length of 20 inches and width of 12 inches. What is the correct multiplication of a cross product to solve for the missing dimension?

The new rectangle is 20 times larger than the original rectangle.

So multiply both length and width of smaller rectangle with 20 to get larger rectangle

x=1

Step-by-step explanation:

Lenght of smalled rectangle = x

Width of smaller rectangle = 3/5 inches

Lenght of larger rectangle = 20

Width of larger rectangle = 12

Find the ratio of width of large rectangle to small rectangle: : 20

Divide length of larger rectangle with 20 to find x:  

d (5 x (-20)) * (100 x (0.7))

step-by-step explanation:

5÷1/100 * -.7 *-20

copy dot flip

5*100 * -.7 *-20

rearrange

5*-20   * 100 *-.7

-100   *-70
