Question

19. The perimeter of a rectangular field is 240 m and the
ratio between the length and breadth is 5:3. What
is the area of field?
27
( 2370 m2
(b) 3795 m2​

Answer 1

Answer:2*(l+b)=peri

2*(5x+3x)=240

2*8x=240

X=240/16=15

So l=75m;b=45m

Area of rectangle=l*b so 75*45=3375m2

Hope it helps

Answer 2

Hey!Here is your answer

Let the length and breadth be 5x and 3x

According to the question

2(5x+3x)=240m

2×8x=240m

16x=240m

x=240m/16

=15m

so, l= 5×15= 75

b= 3×15= 45

so, the area of the rectangle = l×b

= 75×45

= 3375m

Hope this helps
