Question

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

Answer 1

let the breadth is x
then length = 15/100+ x
3/20 + x
23/ 20x

area of rectangle = l* b
23 / 20x * x = 460

23 / 20x^2 = 460

x^2 = 460 * 20 / 23

x^2 = 20 * 20

x^2 = 400

x = 20

breadth = 20cm
length = 23 cm
