Question

The area of a rectangle is 460cm2 if the length is 15percent more than the breadth what is the breadth of the rectangle

Answer 1

Answer:

20cm

Step-by-step explanation:

Let breadth = a

length is 15% more then,

l = a+(a x 15/100)

area= l x B

460=a [a+(a x 15/100)]

460=a^2+15a^2/100

460=(100a^2+15a^2)/100

46000=115a^2

400=a^2

a=20cm
