Question

The width of rectangular hall is 3/4 of it's length.if the area of the hall is 300 m* then the diffrence between it's length and width is

Answer 1

Answer:

The difference is 5m.

Step-by-step explanation:

Let, the lenght of rectangular hall is x m

the width of rectangular hall is 3x/4m

Now, the are of hall is 300m²

The equation is

lenght × width = area

or, x*3x/4 = 300

or, 3x² = 1200

or, x² = 400

or, x = 20

So, the lenght is = 20m

the width is = 3(20)/4 = 60/4 = 15m

So, the difference is = (20-15) = 5m

here is your answer.
