Answer:

x = 16.8

Step-by-step explanation:

The ratio of corresponding sides is equivalent to the ratio of the perimeters.

Then using proportion

\frac{12}{x} = \frac{5}{7} ( cross- multiply )

5x = 84 ( divide both sides by 5 )

x = 16.8

a = 84 - 20 (subtracted 20 on both sides)

a = 64 (calculated 84-20)
