A. 4.7 cm

B. 1.9 cm

C. 5.4 cm

D. 3.5 cm

Answer 1

Hello,

Let's x the length of the second rectangle:

x/14=3/9==>x=14/3==>x=4.666666......
Answer A

Answer 2

A. 4.7 cm

Explanation:

where the rectangles are similar, the ratios of the sides must be similar

Given that One has a length of 14 cm and a width of 9 cm, and the other has a width of 3 cm

let the length of the other rectangle be L

14/9 = L/3

L = (14 × 3)/9

= 14/3

= 4.66cm

≈ 4.7cm

The right option is A. 4.7 cm
