area = 6 X 6 X 4=144 cm ^ 3
That will depend on its dimensions of which none have been given but if they are 2 by 9 then its perimeter is 22 cm or if they are 3 by 6 then its perimeter is 18 cm
The perimeter is 60 mm
Example 1:Find the perimeter of a triangle with sides measuring 5 centimeters, 9 centimeters and 11 centimeters.Solution:P = 5 cm + 9 cm + 11 cm = 25 cmExample 2:A rectangle has a length of 8 centimeters and a width of 3 centimeters. Find the perimeter.Solution 1:P = 8 cm + 8cm + 3 cm + 3 cm = 22 cmSolution 2:P = 2(8 cm) + 2(3 cm) = 16 cm + 6 cm = 22 cmIn Example 2, the second solution is more commonly used. In fact, in mathematics, we commonly use the following formula for perimeter of a rectangle:, where is the perimeter, is the length and is the width.In the next few examples, we will find the perimeter of other polygons.Example 3:Find the perimeter of a square with each side measuring 2 inches.Solution:= 2 in + 2 in + 2 in + 2 in = 8 inExample 4:Find the perimeter of an equilateral triangle with each side measuring 4 centimeters.Solution:= 4 cm + 4 cm + 4 cm = 12 cmA square and an equilateral triangle are both examples ofregular polygons. Another method for finding the perimeter of a regular polygon is to multiply the number of sides by the length of one side. Let's revisit Examples 3 and 4 using this second method.Example 3:Find the perimeter of a square with each side measuring 2 inches.Solution:This regular polygon has 4 sides, each with a length of 2 inches. Thus we get:= 4(2 in) = 8 inExample 4:Find the perimeter of an equilateral triangle with each side measuring 4 centimeters.Solution:This regular polygon has 3 sides, each with a length of 4 centimeters. Thus we get:= 3(4 cm) = 12 cmExample 5:Find the perimeter of a regular pentagon with each side measuring 3 inches.Solution:= 5(3 in) = 15 inExample 6:The perimeter of a regular hexagon is 18 centimeters. How long is one side?Solution:= 18 cmLet represent the length of one side. A regular hexagon has 6 sides, so we can divide the perimeter by 6 to get the length of one side ().= 18 cm ÷ 6= 3 cmSummary:To find the perimeter of a polygon, take the sum of the length of each side. The formula for perimeter of a rectangle is: . To find the perimeter of a regular polygon, multiply the number of sides by the length of one side.
6x4 has a perimeter of 2*(6+4) = 2*10 = 20 cm 6.5x2 has a perimeter of 2*(6.5+2) = 2*8.5 = 17 cm So the first has the larger perimeter.
the answer is 16 cm and that is the perimeter.
24cm (4 sides x 6 = 24)
3 x 4 x 6 = 72 cubic centimeters
The width of the rectangle is 4 cm

Draw it with dimensions of (6 cm) by (3 cm).
6cm. The perimeter of the rectangle has to add to 20. 4+4+6+6=20 Hope this helps ;-)
area = 6 X 6 X 4=144 cm ^ 3
It is: 24/6 = 4 cm
Each side of the square would be 6 centimeters, becasue the area is 6 x 6 = 36 cm. So the perimeter of the square is 6 cm x 4 sides = 24 cm long.
That will depend on its dimensions of which none have been given but if they are 2 by 9 then its perimeter is 22 cm or if they are 3 by 6 then its perimeter is 18 cm
