The Length and Breadth of a Rectangle are in ratio 3:4 . The perimeter of Rectangle is 70 , The dimensions are

Answer»

$\large\bf\underline {To \: find:-}$

$\large\bf\underline{Given:-}$

$\huge\bf\underline{Solution:-}$

Let length and breadth of rectangle be 3x and 4x.

we know that,

$\red{\bf\:perimeter\:of\: rectangle= l\times{b}}$

where,

➻ 2( 3x + 4x ) = 70

➻ 7x = 70/2

➻ 7x = 35

➻ X = 35/7

➻ x = 5

Hence,

● Length of rectangle 3x = 3× 5 = 15

● Breadth of rectangle 4x = 4 × 5 = 20

⠀⠀༒Some formulas :-

⪼ Area of rectangle = l × b

⪼ Perimeter of rectangle = 2(l + b)

⪼ Length of rectangle = Area/Breadth

⪼ Breadth of rectangle = Area/length

⪼ DIAGONAL of rectangle = √l² + b²
