1.	The length and breadth of a rectangle are in the ratio 3:2. If the area of the rectangle is 216sq.m, then find the length of the rectangle and also find the perimeter.
Answer» wer :-<P> Let the length be 3x and breadth be 2x. We know that, Area = Length × Breadth Substituting the values :- → 216 = 3x × 2x → 216 = 6x² → x² = 216 / 6 → x² = 36 → x = 6 Length = 6 × 3 = 18 m Breadth = 6 × 2 = 12 m → PERIMETER = 2 ( Length + Breadth ) → P = 2 ( 18 + 12 ) → P = 2 ( 30 ) → P = 60 Perimeter of RECTANGLE = 60 m

wer :-<P>

Let the length be 3x and breadth be 2x.

We know that,

Area = Length × Breadth

Substituting the values :-

→ 216 = 3x × 2x

→ 216 = 6x²

→ x² = 216 / 6

→ x² = 36

→ x = 6

→ PERIMETER = 2 ( Length + Breadth )

→ P = 2 ( 18 + 12 )

→ P = 2 ( 30 )

→ P = 60
