Question

the length of the rectangle is 10 meter more than its breadth if area of rect angle is 315 cm square find length and breadth​

Answer 1

Answer:

Letthebreadth=xcm

length=x+10

Perimeter=80m

2(l+b)=80m

l+b=40

x+10+x=40

x=15cm

then,length=15+10=25

l=25cm

Dimension(l,b)=(25cm,15cm)

area=l×b

=25×15

=375cm
