The perimeter of the rectangle is 3 m 64 cm, which is the sum of the lengths of its unequal sides.

Let x be the length of the rectangle and y the width, then the perimeter is expressed by the formula: P = 2 (x + y)
By condition, it is known that P = 3m64cm = 364cm
You need to find the sum of two unequal sides, that is, x + y
P = 2 (x + y) = 364cm
X + y = 182cm
Answer: the sum of two unequal sides is 182cm
