The length of a rectangle is 20 cm more than it breadth. if the perimeter is 100 cm. Find the dimension of the rectangle

Answer»

ong>Step-by-step explanation:

LET BREADTH be x

lenght=x+20cm

by the QUESTION,

perimerter=2(l+b)

100cm=2(x+20+x)

100cm÷2=2x+20

50=2x+20

50-30=2x

20=2x

x=20/2=10cm

breadth of rectangle=10cm

lenght of rectangle=x+20

=10+20=30cm

area=l×b

=30×10=300cm2

i hope its help you
