Step-by-step explanation:

Question Ist :

Let,

The consecutive even numbers :

  • x
  • x + 2
  • x + 4

According to the question:

⇒ x + (x + 2) + (x + 4) = 96

⇒ 3x + 6 = 96

⇒ 3x = 96 - 6

⇒ 3x = 90

⇒ x = 90 / 3

x = 30

x + 2 :

⇒ 30 + 2

32

x + 4 :

⇒ 30 + 4

34

Therefore,

The consecutive even numbers are 30, 32, 34

Question II nd :

Let,

Width = x

Length = 2x + 3

Perimeter = 246 m

⇒ 2 (length + width ) = perimeter of rectangle

⇒ 2 ( 2x + 3 + x) = 246

⇒ 2 (3x + 3) = 246

⇒ 6x + 6 = 246

⇒ 6x = 246 - 6

⇒ 6x = 240

⇒ x = 240 / 6

x = 40

Length = 2x + 3 :

⇒ 2 (40) + 3

⇒ 2 × 40 + 3

⇒ 80 + 3

83

Therefore,

The length is 83 m

The width is 40 m
