Question

The area of a rectangle is 460 cm². If the length is 15% more than the breadth, what is the breadth of the rectangle?

Answer 1

Area =
$460cm {}^{2}$
Breadth=x
Length=
$x + \frac{15x}{100}$
=
$\frac{23x}{20}$
A.T.Q

$460 = x \times \frac{23x}{20}$
$23 {x}^{2} = 9200$
${x}^{2} = \frac{9200}{23}$
$x = 20cm$
Breadth= 20 cm
Length=
$20 + \frac{15}{100} \times 20$
=23

Answer 2

Let breadth =x met.

Then length =(115x/100)met.

=x∗115x100=460

x^2=(460x100/115)

x^2=400

x=20
