Question

consider the enlargement of the rectangle.
what is the correct multiplication of a cross product to solve for the missing dimension?
(3/5)(x)=12(20)
(3/5)(20)=12(x)
20 + 12=(3/5)+x
(3/5)+20=12+x

Explanation:

Step1: Set up proportion

For similar rectangles, the ratios of corresponding sides are equal. So, \(\frac{3/5}{12}=\frac{x}{20}\).

Step2: Cross - multiply

Cross - multiplying gives \((3/5)\times20 = 12\times x\).

Answer:

\((3/5)(20)=12(x)\)
