Question

The perimeter of a rectangle is 150cm. Its breadth is 25cm, find it's area.​

Answer 1

Answer:

1250 is the answer.

Step-by-step explanation:

perimeter =2(l+b)

150=2(l+25)

150=2l+50

2l=150-50

2l=100

l =50.

Area =l*b

=50*25

=1250.

Answer 2

Answer:

Area=1250cm²

Step-by-step explanation:

given:-

(i) breadth=25cm

(ii) perimeter=150cm

ATQ,

2×(l+b)=150

l+b=150/2

l+25=75

l=75-25

l=50cm

Now,

Area=l×b

=50×25

=1250cm²
