Question

Perimeter of a rectangular field is 420 M and its length is 120 M find its breadth

Answer 1

hello friend!

here's your answer...

given the length of the rectangular field is 120m.

area of the rectangular field =420m²

l×b=420m²

120×b=420m²

b=420/120

b=3.5m

verification:-

area of rectangular field=l×b

=120×3.5

=420m²

hence verified

thus the breadth of the rectangular field is 3.5m

hope this helps...!

Answer 2

p=420
l=120
                         420=2( 120+x)
                         420/2=(120+x)
                         210=120+x
                        210-120=x               
                        90=x
