Question

A man walks along a rectangle whose perimeter is six km . If the area of the rectangle is two sq.km .what is the breadth of the rectangle?
(1)
$\frac{1}{2} km$
(2)1km
(3)
$1 \times \frac{1}{2} km$
(4)2km

​

Answer 1

Answer:

1 km

Step-by-step explanation:

Let the length and breadth be x and y respectively

A/q

2(x+y)=6

(x+y)=3

x=3-y

and

x×y=2

x=2/y

x=x

3-y=2/y

=>y=1

x=2/y

=2/1

=2

x=2 and y=1

Breadth is 1 km
