Question

1

The breadth and length of a rectangle are in the ratio 4:5 and its area is 320 cm2

. What are

the breadth and length?​

Answer 1

Step-by-step explanation:

Let breadth be 4x and length be 5x.

Area of rectangle = length × breadth

Also, area = 320 cm²

Thus,

4x × 5x = 320

20x² = 320

x² = 16

x = 4

So,

length = 4 × 4 = 16 m

breadth = 5 × 4 = 20 m
