• # question_answer The figure shown is made up of 6 identical rectangles. If its perimeter is 108 cm, find the breadth of each rectangle. A)  10 cm             B)    15 cm C)    7 cm               D)    28 cm

From the figure, clearly the length of each identical rectangle $=\text{ 2}0\text{ cm }\div \text{ 2 }=\text{ 1}0\text{ cm}$ Perimeter of the given figure = 8 lengths + 4 breadths $=\text{8}\times \text{1}0+\text{4}\times \text{breadth}=\text{1}0\text{8 cm}$ $\therefore$ $\text{4 }\times \text{breadth}=\text{ (1}0\text{8}-\text{8}0\text{) cm }=\text{28 cm}$ $\therefore$Breadth $=\text{ 28 cm }\div \text{ 4}=\text{7 cm}$
