Question

the perimeter and length of a rectangle are 300 cm and 100 cm respectively. find its area .
​

Answer 1

Answer:

perimeter=300cm

length=100cm

p=2(l+b)

300=2(100+b)

300/2=100+b

150=100+b

150-100=b

this implies,

b=50cm

area=l*b

area=100*50

area=5000 sq. cm

Answer 2

Step-by-step explanation:

as the perimeter is =300 cm

and the length is = 100 cm

we need to find area

but first we need to find the breadth

2(l+b)=perimeter

2 (100 + b  )  =  300

200  +   2b  =  300

2b  =  300 - 200

2b  =  100

b = 100/2

therefore breadth is 50 cm

area of the rectangle = l*b

= 100*50

therefore the area = 5000 cm ^2
