Question

The ratio between length and breathe of rectangular plot is 5:3 respectively and it's perimeter is 48 m .What will be it's area (in sq m)?

Answer 1

Answer:

let the length and breadth of rectangular plot be 5x and3x A.T.Q

perimeter of rectangular plot =2×(l+b)

48m =2×(5x+3x)

48m = 2×8x

8x = 48÷2

8x = 24

x = 24÷8

x = 3

length = 5x =5×3=15m

breadth =3x = 3×3=9m

now,

area of rectangular plot = (l×b)

= (15×9)sq metre

= 135sq metre

Answer 2

Answer:

perimeter =48

Step-by-step explanation:

5x +3x = 48

8x =48

x=8

length=5x=5×6=30

breath=3x=3×6=18

area of rectangle =l x b

=30×18=540 m
