• # question_answer The figure given is formed using five ^^ identical rectangles. The perimeter of the figure is 66 cm. Find the perimeter of each rectangle. A)  30 cm B)                            15 cm C)  18 cm             D)    135 cm

$\therefore$ Length of the figure = 3 units Breadth of the figure = 2.5 units Perimeter$~=\text{2 (3}+\text{2}.\text{5)}$ units $=\text{2}\times \text{5}.\text{5}$ = 11 units Given perimeter = 66 cm 11 units = 66 cm So, 1 unit $=\frac{6\text{6 cm}}{11}=\text{6 cm}$ $\therefore$ Length of each rectangle = 9 cm Breadth of each rectangle = 6 cm $\Rightarrow$ Perimeter $=\text{ 2}\times (\text{9}+\text{6})\text{ cm}$ $=\text{2}\times \text{15 cm}=\text{3}0\text{ cm}$ Hence, the perimeter of each rectangle is 30 cm.
