This problem has two unknowns, so you will have to solve it using the equation.
We denote one side by X.
The second, since it is 14 cm less, then X-14.
Let’s make an equation.
X + X – 14 = 42.
2 X = 42 + 14.
2 X = 56.
X = 56: 2.
X = 28 cm (first side).
X – 14 = 28 – 14 = 14 cm (second side).
Answer: the sides of the rectangle are 28 cm and 14 cm.
