Question

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

Answer 1

Answer:

Given:-

Area of Rectangle is 460cm² = l × b

Let breadth = X and

Length = X + 15X/100

Step-by-step explanation:

Area of Rectangle = l × b

460 = X × [X + (15X/100)]

460 = X × 23X/20

460 = 23X² / 20

460 × 20 = 23X²

9200 = 23X²

9200 / 23 = X²

400 = X²

20 = X

Hence breadth = 20cm
