Question

Имееться линейка длиной 20 см длина стола больше длины линейки в 5 раз а его ширина больше трёхкратной длины линейки на 13 см вычислите длину и ширину стола

Answer 1

Длина = 20 х 5 = 100 ( см ) 
Ширина = 20 х 3 + 13 = 60 + 13 = 73 ( см )

Answer 2

Problem Analysis

To solve this problem, we need to find the length and width of a table given that the length of the table is 5 times the length of a ruler and the width of the table is 3 times the length of the ruler plus 13 cm.

Solution

Let's assume the length of the ruler is x cm. According to the problem, the length of the table is 5 times the length of the ruler, which can be expressed as 5x cm. The width of the table is 3 times the length of the ruler plus 13 cm, which can be expressed as 3x + 13 cm.

Therefore, the length of the table is 5x cm and the width of the table is 3x + 13 cm.

To find the values of x, 5x, and 3x + 13, we need to know the length of the ruler.

Conclusion

To calculate the length and width of the table, we need to know the length of the ruler. Once we have that information, we can use the formulas 5x cm for the length and 3x + 13 cm for the width, where x is the length of the ruler in centimeters.
