Question

the area of a rectangle is 460cm2 if the lenght is 15% more than the breadth what is the breadth of the rectangle??

Answer 1

Question;-

The area of a rectangle is 460cm2 if the lenght is 15% more than the breadth what is the breadth of the rectangle??


Method of Solution;-

Let to be Breadth of rectangle = x


Given;-

Area of Rectangle = 460cm²

Length is 15% more than the breadth.
According to the Question!!

•°• Length will be = (100+15 )x/100

We know that;- Area of Rectangle = Length× Breadth

Now, Substitute the Given value in Equation!!


Area of Rectangle = Length× Breadth

460 = 115x/100 + x

•°• x² = 460 × 100/115

x² = 46000/115

x² = 400

•°• x =√400

•°• x = 20


Hence, Breadth will be = 20 Centimeters.

Answer 2

Here is your Solution

Given:-

Area of Rectangle = 460cm²

Let  Breadth of rectangle to be  x

Length is 15% more than the breadth.

A/q

Length = (100+15 )x/100

We know that

Area of Rectangle = Length× Breadth

Now,

putting  the Given value of Length

Area of Rectangle = Length× Breadth

=>460 = 115x/100 ×  x

=>x² = 460 × 100/115

=>x² = 46000/115

=>x² = 400

=> x =√400

=> x = 20

Hence,

Breadth  = x = 20cm
