if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
if you have a box that is 9cm long and 3cm wide then you would say width + length + width + length because the side opposite from 3cm is also 3cm and the side opposite 9cm is also 9cm. so you would add: 9cm+9cm+3cm+3cm = 24cm
Well, honey, making a shape with a perimeter of 9cm is as easy as pie. You could have a triangle with sides measuring 3cm, 3cm, and 3cm. Or you could have a rectangle with sides measuring 2cm and 2.5cm. Just remember, the perimeter is the sum of all the sides, so get those measuring tapes out and get creative!
9cm + 5cm + 9cm + 5cm = 28cm
Add all the sides of the irregular figure to the obtain the perieter. In the this particular case the permeter will be 2+3+4+9 =18 cms.
Area = (length of a side)2 = 81 square centimeters Perimeter = 4 x (length of a side) = 36 cm.
28 cm

it is 81cm
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 9cm and the width is 3cm. So, the area of the rectangle would be 9cm x 3cm = 27 square centimeters.
To find the perimeter of a regular pentagon with 9cm sides, you would multiply the length of one side by the total number of sides. In this case, 9cm x 5 sides = 45cm. Therefore, the perimeter of a regular pentagon with 9cm sides is 45cm.
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
3cm x 9cm = 27cm2 (27 square centimetres)
Think about two numbers whose multiplication is 9 or simply think about the factors of 9. Factors of 9 are 3x3 Now see perimeter of rectangle is 2 times sum of length and breadth. Perimeter of rectangle is 4 times side. 2 and 4 are of the factors of 9. So the figure cannot be rectangle or square. Perimeter of triangle= Sum of all sides 9 = 1+3+5 =9 Hence it is possible to have a triangle with perimeter 9cm as there are various numbers whose addition could be 9. So the figure could be triangle.
63 cmPerimeter = 2 x (Length + Width) = 2 x (9cm + 7cm) = 2 x 16cm = 32cm
9cm + 5cm + 9cm + 5cm = 28cm
Area = π x R2Area = (3.14) x (3cm)2Area = (3.14) x (9cm)Area = 28.26 cm2
135cm
The area of rectangle is : 18.0
