Sum of my Length and  Breadth is 36. I am a rectangle. My  Length is x units and  breadth is y units The difference  between my length  and breadth is 6  units.​

Answer»

ong>Answer:

  • Length and breadth of the rectangle are 21 units and 15 units respectively.

Step-by-step explanation:

Given that:

A rectangle having,

  • Length = x units
  • Breadth = y units

Sum of length and breadth = 36 units

  • i.e., x + y = 36 _____(i)

DIFFERENCE between length and breadth = 6 units

  • i.e., x - y = 6 _____(II)

To Find:

  • Length and breadth of the rectangle.

FINDING the length and breadth:

ADDING eqⁿ(i) and eqⁿ(ii).

⟶ (x + y) + (x - y) = 36 + 6

⟶ x + y + x - y = 42

Cancelling y.

⟶ 2x = 42

⟶ x = 42/2

⟶ x = 21

∴ Length of the rectangle = 21 units

In EQUATION (ii).

⟶ x - y = 6

Putting the value of x.

⟶ 21 - y = 6

⟶ y = 21 - 6

⟶ y = 15

∴ Breadth of the rectangle = 15 units
