Question

If the length of a rectangle is 5 less than 9 times the breadth, and the perimeter of a rectangle is 750 meters, the length of rectangle is _____​

Answer 1

Answer:

337m

Step-by-step explanation:

Let length=l

breadth=b

Given,

l=9b-5 and

perimeter=750 m

Perimeter of rectangle = 2(l+b)

2(l+b)=750

2(9b-5+b)=750

10b-5=375

10b=380

b=38m

So, l=9(38)-5=342-5=337
