Question

please answer my question I need the answer urgent.​

Answer 1

Step-by-step explanation:

let the breadth be X

length= 3x

perimeter=2[l+b]

1960cm= 2(X+3x)

= 2x+6x

1960 = 8x

X= 245cm

breadth= 245cm

length= 3*245= 735cm

area= l*b= 245*735

= 180075cm

100cm = 1 metre

180075cm = 1800.75 m square.

Answer 2

Answer:

18.0075m^2

Step-by-step explanation:

Let length and breadth be x then..

Given = length=3x

and breadth=x

Perimeter=1960cm

1cm=1/100m so 1960 cm = 1960/100=19.6 metre

In a rectangle.. Perimeter=2(l+b)

=2(3x+x) =2(4x) =8x

so 8x=19.6m

x=19.6/8=2.45m

Hence we find the value of x and we can find length and breadth.

Length=3x=3×2.45=7.35

Breadth=x=2.45

Now we have find length and breadth all we need to find is area

Area of rectangle=length×breadth

=7.35×2.45=18.0075m^2

Here is your answer..
