| The solution of the problem:
Perimeter – 160 cm
Let’s take the width as x
Then (x + 10) will be the length.
Let’s make an equation.
2 * (x + x + 10) = 160
x + x + 10 = 160/2
2x + 10 = 80
2x = 80 – 10
x = 70/2
x = 35cm – rectangle width
35 + 10 = 45cm – the length of the rectangle
Answer: the length of the rectangle is 45cm
