Answer 1

Answer:

mark me BRAINLIEST and some thnx please don't forget

Step-by-step explanation:

breadth=b

length =b²

area of rectangle = 2( l+ b)

=2( b²+b)

=2(2b²)

=4b²

Answer 2

Answer:

area = 10b

Step-by-step explanation:

area of rectangle = 2(length + breadth)

# examine the length as 'x'

area of rectangle = 2(x + b)

# find out x

x = 4*b

x = 4b

# now find area of rectangle

area of rectangle = 2*5b

area of rectangle = 10b
