Question

Two rectangles are similar. One has a length of 11 cm and a width of 10 cm, and the other has a width of 7 cm. Find the length of the second rectangle. Round to the nearest tenth if necessary.

Answer 1

The answer would be 7.7 cm

Answer 2

Answer:

The length of the rectangle is 7.7 cm.

Step-by-step explanation:

When two rectangle are similar then the ratio of their length is equal to the ratio of their width,

Given,

The length of one rectangle = 11 cm,

Its width = 10 cm,

Also, the width of the second rectangle = 7 cm,

Let l be the length of the second rectangle,

By the above property,

$\frac{l}{11}=\frac{7}{10}$

$\implies l = \frac{77}{10}=7.7\text{ cm}$

Hence, the length of the second rectangle is 7.7 cm.
