Answer 1

Answer:

Step-by-step explanation:

Let breadth be b

then length= 2b

here breadth=6cm

then length= 12cm

area= Length ×Breadth

area=12× 6 cm²

area=72cm²

Answer 2

Answer:

72 sq.cm

Step-by-step explanation:

so the book is a rectangle

book-

l = 2b

b =6t

therefore 2b =2 into 6 which is 12

so l=12

b =6

Area of the book =b into l which is 6 x 12 which is 72 sq.cm

Thus area of the book is 72 sq.cm
