• # question_answer Figure A is a rectangle measuring 15 cm by 9 cm. Figure B is made up of 3 identical squares. Both the figures, A and B, have the same perimeter. Find the side of the square. A)  10 cm                         B)  6 cm   C)    36 cm             D)    64 cm

Perimeter of rectangle $\text{A}=\text{2}\times (\text{15}+\text{9})=\text{48 cm}$ Side let each side of square = S Perimeter of figure $\text{B}=\text{8}\times \text{6 S}$ Given perimeter of figure A = Perimeter of figure B $\text{48 cm}=\text{8}\times \text{S}$ $\therefore$ $\text{S}=\text{4 cm}\div \text{8}=\text{6 cm}$
