Question

If the perimeter of a rectangular field is 240 m if its length is 90 m find (1) its breadth (2) its area

Answer 1

Answer:

Perimeter of rectangular field = 90+90+breadth+breadth....2 breadth can be written 2x

240 = 180+2x

240-180=2x

20=2x

x=20

2

X=10

Hence the breadth is 10m

Area of rectangular field= l×b

=90×10

=9000m
