Answer 1

Answer:

here's your answer

Step-by-step explanation:

p=2(l+b)

100=2l+40

2l=60

length =30

area = l*b

=30*20

=600cm²

hope it helps

Answer 2

Answer:

600cm²

Step-by-step explanation:

Given, perimeter= 100cm

breadth= 20cm

length= 2( l + 20)cm = 100cm

= 2l + 40cm = 100cm

= 2l = 100- 40= 60cm

= l = 60/ 2 = 30cm

Therefore, area of rectangle= l × b= 20 × 30 cm = 600cm²
