Question

two similar rectangles are shown below. the larger rectangle is 1.6 times the size of the smaller rectangle. what is the value of x?
7 ft
4 ft
x
6.4 ft
a. 14 feet
b. 16.8 feet
c. 4 feet
d. 11.2 feet

Explanation:

Step1: Use similarity ratio

Since the larger rectangle is 1.6 times the size of the smaller one, we multiply the corresponding side of the smaller rectangle by 1.6. So $x = 7\times1.6$.

Step2: Calculate value of x

$x=7\times1.6 = 11.2$

Answer:

d. 11.2 feet
