Question

The length of a rectangular field is twice it's breadth. If the perimeter of the field is 150 metres, finds its length and breadth.

Answer 1

Answer:

length=50m,breath=25m

Step-by-step explanation:

let the breath of rectangle be x

so, length of rectangle be 2x.

perimeter of rectangular field=150m

2(l+b)=150

2(2x+x)=150

2x+x=150/2

3x=75

x=75/3

x=25

so, length of rectangular field=2x=2×25

=50

breath of rectangular field=x=25

Answer 2

Answer:

Let the breath(b) = x

length is twice than breadth, so length(l) will be

=2x

The perimeter of the rectangle =150m

perimeter=>2×(l+b)=150

=2×(2x+x)=150

=>2×3x=150

=>3x =150/2

=> x =75/3

=> x =25

so, length will be 2x =2×25=50

similarly, breadth will be equal to x=1×25=25.

Thus, length and breadth equal to 50, 25 respectively.
