Question

the length and breadth of a rectangular field are in the ratio 5 is to 3 and its perimeter is 480 M then find the area of the field

Answer 1

Let the common multiple be x.Then,length=5x and breadth=3x.
We know that,
perimeter of rectangle=2 (l+b)
480=2 (5x+3x)
480=10x+6x
480=16x
x=480/16
x=30.
length=5x=150m.
breadth=3x=90m.
we know that,
area of rectangle=length×breadth
=150×90
=13500m2.
so,area is 13500m2.
hope it helps you.Please mark as brainliest.

Answer 2

Answer:

13500m

Step-by-step explanation:

perimeter of rectangle=2(l+b)

480=(10x+6x)

480=16x

x=480/16

x=30

area of rectangle=l*b

=150*90

=13500
