Answer 1

hey there here's your answer :-

Answer :-

first find length by this process

= (Length + Breadth) = 1/2 × Perimeter

= (Length + 20) = 1/2 (2 cut) = 50

= (Length + 20) = 50

= Length = (50 - 30) = 30

= Length = 30

For Verification :-

=> 2 × (Length + Breadth)

=> 2 × (30 + 20)

=> 2 × 50

=> 100 cm

So, The Length is 30 cm

Now we will find Area

Area :-

Formulae used :-

=> Length × Breadth

=> 30 × 20

=> 600 sq.cm
