Question

Shipra runs along a rectangular field twice and covers a distance of 540m if the length of the field is 75m find it's area​

Answer 1

Step-by-step explanation:

dist covd. 540m

length. 75m

area.=2(l+b)

=153.6m.square

Answer 2

Answer:

Area=4500 m^{2}

Step-by-step explanation:

As we have given in the question there is a rectangular field of which length=75 m and Shipra runs along with it twice i.e. she makes 2 round of it.

So we have given the perimeter=540 m and we know perimeter

=$2(l+b)$, As she covers 2 rounds we multiply perimeter by 2

Therefore perimeter=$4(l+b)$

Now putting all these values for the same

$4(75+b)=540$

$75+b=135$

$b=135-75=60$

Now as we know breadth=60 m we have to find its area i.e.

$l\times b$

Area=$=75\times60=4500m^{2}$
