Question

the area of a rectangle is 460 CM square if the length is 15% more than the breadth what is the breadth of the rectangle

Answer 1

area=450cm
Length=b+0.5cm
breadth=b
=450÷2
=225
=l=225
b=225-5
= 220

Answer 2

Let breadth =x met.

Then length =(115x/100)met.

=x∗115x100=460

x^2=(460x100/115)

x^2=400

x=20
