This is one of those areas where there is ambiguity.
A 9 cm square is a square whose sides are 9 cm and which therefore has an area of 81 cm2.
But 9 cm2 represents an area of 9 square centimetres. The shape of this area is unspecified.
When written in the above form, the ambiguity is less obvious but in spoken form it is.
9cm
Area = length x width. In a square these are the same so it is the square of a side, in this case the square of 9...
18 square cm
9cm + 5cm + 9cm + 5cm = 28cm
there are 10mm in a cm, so 88mm is closer to 9cm because it is 8.8cm

81 square centimeters
31 centimeters
Area for square is Base X Height. Since the length is all equal FOR a square The base and height is both 9cm So the answer is 81cm
Area is length times width. So... 9x9=81
81 square cm's
ok if the perimeter is 36cm and it is a square then you know all four sides are equal 36cm / 4sides = 9cm for each side A = L * W ( both the length and width are 9cm because each side is equal ) A = 9cm * 9cm A = 81cm2
254.47 square cm
To find the area of a rectangle, you multiply the length by the width. In this case, the width is 7cm and the length is 9cm. So, the area would be 7cm x 9cm = 63 square centimeters.
any 2-D shape could have a perimeter of 9cm. One example is a square with sides of 9/4 cm.
