Answer:

202.5cm^2

Step-by-step explanation:

P=2l+2w

63=2(9)+2w

63=18+2w

63-18=2w

45=2w

divide both sides by 2

22.5=w

check:

P=2(9)+2(22.5)

=18+45

=63

Area=l×w

=22.5×9

=202.5cm²

Answer:

A = 202.5 cm²

Step-by-step explanation:

P = 63 = 2×9 + 2w

2w = 63 - 18

2w = 45

w = 22.5 cm

A = w×l = 9×22.5 = 202.5 cm²
