Question

if the length of rectangle is thrice the breadth the area of rectangle is 27msquare then the length of breadth are

Answer 1

let the breadth be x.
so length=3x
area of rectangle= l×b
3x×x=27
${3x}^{2} = 27$
${x}^{2} = 9$
$x = \sqrt{9}$
$x = 3$
$length = 9cm \\ bredth = 3cm$

Answer 2

HEY MATE..
HERE'S UR ANSWER..

Let the breadth = x
& length =3x


➡Area of rec. =( l × b ) u^2

➡27m^2 = 3x × x

➡27m^2 = 3x^2

➡27m^2 ÷ 3 = x^2

➡9m^2 = x^2

➡√9m^2 = x

➡3m = x

▶Breadth = 3m

▶Length = 3m × 3 = 9m
