How many cm is 2 m greater than the sum of 80 cm and 90 cm?
2 meters is 200 centimeters, so... 80 + 90 = 170 centimeters 30 centimeters longer
Is it possible to build a triangle with the lengths of 3 cm 4 cm and 5cm?
Oh, what a happy little question! Yes, it is possible to build a triangle with sides of 3 cm, 4 cm, and 5 cm. This special triangle is called a right triangle, and it follows the Pythagorean theorem where the square of the longest side (5 cm) is equal to the sum of the squares of the other two sides (3 cm and 4 cm). So go ahead and paint that lovely triangle with confidence!
What is the missing side length of an irregular pentagon if pentagon has side lengths of 19 9 cm 24 8 cm 30 cm and 49 2 cm and it has a perimeter of a regular pentagon with side lengths 26 m?
Such a pentagon is impossible. A regular pentagon, with side lengths of 26 m has a perimeter of 5*26 = 130 metres. Four sides of the irregular pentagon are 19.9 cm, 24.8 cm, 30 cm and 49.2 cm making a total of 123.9 cm. The length of the fifth side must be less than 123.9 cm. Therefore the perimeter of the irregular pentagon must be less than 247.8 cm - less than 2% of the required length of 130 metres or 13,000 cm.
What is the perimeter of a rectangle measuring 9 cm by 4cm?
2 * 9 cm + 2 * 4 cm = 18 cm + 8 cm = 26 cm or 9+9+4+4=26cm
How do you find the scale factor?
A scale factor tells how much the lengths in one diagram must be multiplied by to get the same lengths in a second.One diagram could be a map and the second the real world!To calculate the scale factor, measure the corresponding lengths in the same units and then divide the length of the second diagram by the length of the first diagram; this will give you the scale factor to convert the first diagram into the second diagram.For example, if you were to draw a map of you street, you may decide that 2 centimetres on the map will represent 1 metre in the real world.The ratio here is 2 cm : 1 m.However, 1 m = 100 cm which means that the ratio is 2 cm : 100 cmwhich is a scale factor of 100 cm ÷ 2 cm = 50.Another example: if you have two similar triangles and the corresponding sides measure as 5cm in the first triangle and 2 cm in the second, the scale factor is 2 cm ÷ 5 cm = 2/5 or 0.4
Could 12.2 cm 6.0 cm and 4.2 cm be the side lengths of a triangle?
No because the sum of the 2 smallest sides of a triangle must be greater than its longest side.
What could be the third side of a triangle with side lengths of 4 cm and 6 cm?
The sum of the 2 shorter sides must be greater than the longest side to form a triangle
What would be the perimeter of a rectangle 6 centimeters by 9 centimeters?
2 of the sides are 6 cm and the other two sides are 9 cm. Perimeter = sum of the lengths of the sides = 6 + 6 + 9 + 9 = 30 cm
If 48 cm and 54 cm are the lengths of two sides of the triangle what is the range of possible values of the third side?
The sum of the 2 smallest sides of a triangle must be greater than the length of its longest side
What is the sum of 39 and 2?
41
What is the perimeter of an equilateral triangle that measures 2 cm on one side?
The perimeter (sum of the lengths of the sides) would be 3 x 2 cm = 6 cm *This is actually seeing if one knows the definition of "equilateral triangle", i.e. that all three sides have the same length.
What is the average of 148 and 39?
The average of 148 and 39 is the sum of 148 and 39 divided by 2, or 187/2, or 93.5
How many cm is 2 m greater than the sum of 80 cm and 90 cm?
2 meters is 200 centimeters, so... 80 + 90 = 170 centimeters 30 centimeters longer
What is 5 mm 9 mm 2 cm 2.6 cm?
That is a list of four different lengths.
What is the area of a trapezoid with sides 4 cm and 5 cm and height 3 cm?
To find the area of a trapezoid, you use the formula: Area = (1/2) * (sum of parallel sides) * height. In this case, the sum of the parallel sides is 4 cm + 5 cm = 9 cm. Plugging in the values, we get: Area = (1/2) * 9 cm * 3 cm = 13.5 square cm. Therefore, the area of the trapezoid is 13.5 square cm.
What is the sum of 7and a half cm amd 2 and a half cm?
