Question

In writing the equation to construct a rectangle of specified perimeter and area, the perimeter was wrongly written as 24 instead of 42. The length of a side was then computed as 10 meters. What is the area in the problem? What are the lengths of the sides of the rectangle in the correct problem?​

Answer 1

Answer:

Let the number be x

Then reciprocal of number is

If reciprocal number, subtracted from the number itself is 1

Then;

(x–) = = 1

∴ comparing both

x = 2

x2–1 = 3

x2 = 4

x = √4 = 2

∴ the number is 2

Conclusion/Result. Number comes out to be 2
