Question

The perimeter and length of a rectangle are 300cm and 100cm respectively.Find it's area

Answer 1

Answer:

$5000cm^{2}$

Step-by-step explanation:

The perimeter is 300 and the length is 100 so the other side is 50

50*100 =5000

Answer 2

Answer:

l=100

b=x

p=300

p=2( 100+x)

300=(200+2x)

2x=300-200=100

x=100/2=50

Area=l*b

100*50=5000
