What is the perimeter of an equilateral triangle with 25cm sides?
Perimeter = 3*25 = 75 cm
What is the formula to get the perimeter of equilateral triangle?
There are at least 2 possible answers: (1) 3 times the length of one side (2) If for some reason you don't have the side length but just have the height then you can use the formula: square root(H^2/.75) Where H is the height of the triangle
What is the scale factor of two figures with a perimeter of 50 Cm and 75 Cm?
There need not be any. There is no scale factor between a pentagon with a perimeter of 50 cm and a triangle with a perimeter of 75 cm. The shapes are totally different!The scale factor is 2 : 3.
What is the area and perimeter of a scalene triangle when angle 75 degrees is opposite to side 25cm with another angle of 42 degrees?
Using the sine rule in trigonometry its area is 192.885 square cm and its perimeter is 65.379 cm both rounded to three decimal places.
A triangle has a perimeter of 75cm The longest side is twice as long as the shortest side The third side is 3 cm longer than the shortest side What is the length of the longest side?
2x=y x+3=z x+y+z=75 x+2x+x+3=75 4x=72 x=18 y=36 z=21
Find the area of an equilateral triangle of side 10?
First find the perpendicular height (h) of the triangle using Pythagoras.h = sqrt (102 - 52) = sqrt 75 = 8.660254038...Now, area of a triangle = 1/2 base x height.So: area = 1/2 x 10 x 8.660254038 = 43.3 (1 decimal place.)
Can you show that you can work out the area of a regular hexagon with a perimeter of LX inches rounding your answer to a suitable degree of accuracy?
Perimeter in inches = LX = 60. A regular hexagon with a perimeter of 60 inches has 6 equal sides of 10 inches. A regular hexagon has 6 equal interior equilateral triangles So in order to find the area of the hexagon we must first find the area of one of its interior triangles and then multiply the result by 6. Area of a triangle = base times perpendicular height divided by 2. An equilateral triangle can be considered as being two right angled triangles joined together. So by halving the length of its base we can find its perpendicular height by using Pythagoras' Theorem: hypotenuse2-base2 = perpendicular height2. 102-52 = 75 square inches. Square root of 75 = 8.660254038 inches. Area of the equilateral triangle = 10*8.660254038/2 = 43.30127019 square inches. Area of the regular hexagon = 43.30127019*6 = 259.8076211 square inches. Therefore the area of a regular hexagon with a perimeter of 60 inches is 260 square inches which is correct to 3 significant figures.
What is the perimeter of a rectangle length 75cm by width12?
Perimeter = 174cm (75 +75 +12 +12)
If the Bermuda triangle has a perimeter of 3075 miles shortest side measures 75 mi less than the middle side longest side measures 375 mi more than the middle side find the length of the three sides?
m = middle side lengthshortest side length is 75 miles less than the middle side length m; so, use (m - 75) to represent the length of the shortest sidelongest side length is 375 miles longer than the middle side length m; so, us (m + 375) to represent the length of the longest sideperimeter of the triangle = the sum of all the side lengths3075 = m + (m - 75) + (m + 375)3075 = 3m + 3002775 = 3m925 = m3075 = 925 + (925 - 75) + (925 + 375)Therefore, the lengths of the sides from smallest side to longest side are: 850 miles, 925 miles, and 1300 miles
Can an equilateral have one 75 degree angle?
No because a triangles inner angles must equal a whole 180 degrees and an equilateral has to have all equal interior angles and 75+75+75 does not equal 180
How can you find out the answer of A triangle is 10cm wide and 15cm tall what is the area of the rectangle?
Area of the triangle = 0.5*base*height = 0.5*10*15 = 75 square cm Area of the rectangle = base*height = 10*15 = 150 square cm
What type of triangle has angles of 75 75 and 30 degrees?
An isosceles triangle has angles of 75, 75 and 30 degrees.
