Find the area of a rectangle if the perimeter is 60 cm, and the ratio of adjacent sides is 4:11.

First you need to determine how many centimeters are the sum of the adjacent sides.

To do this, divide the specified perimeter into 2 parts.

60/2 = 30 cm.

Since the sides are related as 4:11, then the sum of equal parts will be equal to:

4 + 11 = 15.

In this case, the length of the first side will be:

4/15 * 30 = 4 * 2 = 8 cm.

The length of the second side will be:

11/15 * 30 = 2 * 11 = 22 cm.

The area of the rectangle is the product of two adjacent sides and in this case is:

8 * 22 = 176 cm2

Answer: 176 cm2
