Question

the length of a rectangular field is three times its breadth if the breadth of a rectangle is 3 whole 1 by 2 metre find the perimeter of rectangle​

Answer 1

Answer:

let the breadth 3whole 1/2

so the length be 3×7/2

=21/2

=length=10.5

perimeter =2(l+b)

=2(10.5+7/2)

=21+7

perimetre=28m

The length of a rectangular field is three times its breadth if the breadth of a rectangle is 3^(½) metre find the perimeter of rectangle.

$\huge\red{\underline{\underline{\bf Answer:-}}}$

$\huge given \: \: that \implies \\ \\ length = 3(breadth) \\ \\ also \\ \\ breadth = {3}^{ \frac{1}{2} } \: \: \: or \: \: \: \sqrt{3} \\ \\ so \: \: length \: \: will \: \: be \implies 3 \sqrt{3} m \\ \\ \large formula:- \\ \\ Perimeter = 2(length + breadth) \\ \\ \implies Perimeter = 2( 3\sqrt{3} + \sqrt{3} ) \\ \\ \implies Perimeter = 2(4 \sqrt{3} ) \\ \\ \huge \boxed{ \implies Perimeter = 8 \sqrt{3} \: \: m}$
