The width of the rectangle is 75% of its length. The length is 8 cm. What is the width of the rectangle?
hjlf

Given :

The length of the rectangle, l = 8 cm/

The width of the rectangle, w = 75% of 8 cm

                                                 $= \frac{75}{100} \times 8$

                                                 $=\frac{15}{20} \times 8$

                                                 = 0.75 x 8

                                                 = 6

Therefore, the width of the rectangle is 6 cm.
