we can use the ratio between the given sides to find the similar rectangle

given 36/9= 4
A-- 30/6=5
B-- 44/11= 4
C-- 64/8= 8
D--72/12=6

As you can see the ratio of B matches with our given rectangle

Answer:

The rectangle which is similar to the given rectangle is:

B) rectangle with a length of 44 and a width of 11.

Explanation:

Two figures are said to be similar if the ratio of each of the corresponding sides of the two figures are equal.

Given a rectangle with a length of 36 and a width of 9.

A)

rectangle with a length of 30 and a width of 6.

The ratio of the corresponding sides is given by:


(36)/(30)=(9)/(6)\\\\(6)/(5)=(3)/(2)

since, the two ratios are not equal.

Hence, the figure are not similar.

B)

rectangle with a length of 44 and a width of 11.

The ratio of the corresponding sides is given by:


(36)/(44)=(9)/(11)\\\\(9)/(11)=(9)/(11)

since, the two ratios are equal.

Hence, the figure are similar.

C)

rectangle with a length of 64 and a width of 8.

The ratio of the corresponding sides is given by:


(36)/(64)=(9)/(8)\\\\(9)/(16)=(9)/(8)

since, the two ratios are not equal.

Hence, the figure are not similar.

D)

rectangle with a length of 72 and a width of 12.

The ratio of the corresponding sides is given by:


(36)/(72)=(9)/(12)\\\\(1)/(2)=(3)/(4)

since, the two ratios are not equal.

Hence, the figure are not similar.
