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
