| The area of the rectangle is S = a * b, S = 16.8 cm ^ 2.
The width of the rectangle is a = 3 [3/5] cm.
Let’s find the length of the rectangle:
3 [3/5] * b = 16.8;
18/5 * b = 16 [8/10];
18/5 * b = 16 [4/5];
18/5 * b = 84/5;
b = 84/5: 18/5;
b = 84/5 * 5/18;
b = 84/18;
b = 14/3;
b = 4 [2/3];
The length is 4 [2/3] cm.
