Question

> The perimeter of a rectangular
sheet is 70cm. If its breadth
is 15cm. Find the length of
and its area​

Answer 1

2(l+b)=p2(l+15)=70l+15=35l=20area=l×b=20×15=300sq.cm 

Answer 2

Answer:

20cm is the length

Step-by-step explanation:

perimeter of a rectangle = 2(l + b)

breadth = 15cm

length = 70  = (2 x l) + (2 x 15) = 2l  + 30

= 2l + 30 = 70

= 2l = 70 - 30

= 40 = 2l

= 40/2 = l

=20cm
