How do you calculate cm2?
To calculate area, or cm2, the length and width must be multiplied. For example, a length of 2 cm and a width of 3 cm equals an area of 6 cm.
What is the width of a rectangle with an area of 34cm2 and length of 9 cm?
Area = length x width ⇒ width = Area ÷ length = 34 cm2 ÷ 9 cm = 37/9 cm ~= 3.78 cm
What is the surface area for 1.5 cm?
A line has no width nor depth, so it has no surface, thus its surface area is 0 cm2
What is the area of a rectangle that has a perimeter of 30 cm and the length is twice the width?
50 cm2
If the length of a rectangular prism is 10 cm width is 5cm and height is 4cm what is the surface?
L = 10W = 5H = 42 faces have area = 502 faces have area = 402 faces have area = 20Total surface area = 220 cm2
How do you measure cm2?
For a rectangle, length X width = area. Measure the length in cm. Measure the width in cm. Multiply the length X the width to get the area in cm2.
A box has a volume of 7500 cm3 and a surface area of 2600 cm2. What are length, width, and height of the box?
30,25,10

What is the width of a rectangle with length 14 cm and area 161 cm2 with the steps please?
area=length*width width=area/length w=161/14 w=11.5
What is the area of a rectangle with a perimeter of 16cm?
Any area you want greater than 0 cm2 and less than or equal to 16 cm2. perimeter_of_rectangle = 2 x (width + length) 16 cm = 2 x (width + length) ⇒ width + length = 8 cm ⇒ length = 8 cm - width Neither dimension can be negative, so they are both greater than 0 cm and less than 8 cm. Area_of_rectangle = width x length ⇒ area = width x (8 cm - width) = 8 x width - width2 cm2 This has a minimum value when width = 0 cm or 8cm of 0 cm2, so the area of the perimeter must be greater than 0 cm2 (as the width can be neither 0 cm nor 8 cm). This has a maximum value when width = 4 cm: max_area = 8 x 4 - 42 cm2 = 16 cm2. when the width is between 0 cm and 4 cm (and so the length is between 8 cm and 4 cm) the area is between 0 cm2 and 16 cm2 When the width = 4 cm, the length is also 4 cm, that is the rectangle is a square.
What is the width of a rectangle with an area of 34cm2 and length of 9 cm?
Area = length x width ⇒ width = Area ÷ length = 34 cm2 ÷ 9 cm = 37/9 cm ~= 3.78 cm
The area of the rectangle is 126 cm2 if the width is 9 cm what is the length?
126 / 9 = 14cmRemember:Area = Length x WidthWhich can be written as...Length = Area / WidthOr...Width = Area / Length
What is the surface area for 1.5 cm?
A line has no width nor depth, so it has no surface, thus its surface area is 0 cm2
If the length of a rectangular prism is 10 cm width is 5cm and height is 4cm what is the surface?
L = 10W = 5H = 42 faces have area = 502 faces have area = 402 faces have area = 20Total surface area = 220 cm2
What is the area of a rectangle with a length of 12 cm and a width of 6.5 cm?
78 cm2
What is the area of a rectangle that has a perimeter of 30 cm and the length is twice the width?
50 cm2
What is the total surface area of a square pyramid that has a base length of 14 cm and the slant length is 25 cm?
Height of side = square root of (625 cm2 + 196 cm2) = 28.65 cm Surface area of 4 sides = 4 x 28.65 cm x 14 cm = 1,604 cm2 Area of base = 196 cm2 Total surface area, including area of base, is 1,800 cm2
