Question

find the bredth of a rectangle if its area is 440 cm² and its breadth is 20 cm.Also find its perimeter​

Answer 1

Answer:

A=l×b

440=l×20

440÷20=l

11cm=l

P=2(l+b)

=2(11+20)

=2×31

=61..

Answer 2

Answer:

Area= l*b

440 = l*20

l=440/20

l= 22 cm

Perimeter = 2(l+b)

=2(22+20)

= 2*42

= 84 cm square
