Question
Find the breadth of the rectangle whose perimeter is 360cm and whose length is:102cm

Perimeter of a rectangle = 2(Length + Breadth)Therefore, Breadth of the rectangle $=\frac{\text{Perimeter}}{2}-\text{Length}$
Perimeter = 360cm Length $=\frac{10}{2}$ Breadth $=\frac{360}{2}-140$ = 180 - 102 = 78cm
