Question

if the perimeter of a rectangle is 180 meters and the difference between the length and the breadth is 8 meters what is the area of the rectangle

Answer 1

Answer:

Let the length be l

Breadth be b

A/Q

perimeter =180m

=》 2(l+b)=180m

=》l+b=180/2m

=》l+b=90m ........(1)

Again ,

=》 l - b =8m.......(2)

(1) - (2) =》l+b+l-b=90-8m

=》2l=82m

<》l=41m

putting the value of l =41 in quation (1)

l+b=90m

41+b=90m

b =90-41= 49m

Therefore area is l×b=41×49=2009m sq.
