Using the cosine rule as in trigonometry the exterior angles of the triangle are 117.81 degrees, 135.56 degrees and 106.63 degrees which all add up to 360 degrees.
They are 118, 136 and 106 degrees, respectively.
The area of a triangle is (base)x(height)x1/2.So, we put in your values (base=19, height=14) and we get 19x14x1/2=19x7=133.The area of a triangle with a base of 19cm and a height of 14cm is 133.
19 x 4 = 76cm
To find the area of a triangle, you need the length of the base and the height. If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.
The perimeter of a rectangle is simply the sum of its four sides. In this case - 12 + 19 + 12 + 19 = 62
I find the area by applying the standard formula for the area of a triangle, which is the length of the base multiplied by the height all divided by two. You should too.
I cut out the lengths to have a visual look at the problem and the answer is NO you cannot arrange 5cm, 12cm, and 19cm into a triangle. Even straightening out the lengths of 5cm and 12cm into a 180 degree angle will not measure out to the 19cm. You cannot have a side that is more than the length of the other two sides combined in a triangle.

19 x 4 = 76cm
add 9cm to10cm and you come up with 19cm is ths correct?
19cm

Using Pythagoras' theorem for a right angle triangle it is 11.662 cm rounded to 3 d.p.
19cm = 7.5" appro.
is 19cm the same as 7.2 inches
1.26m + 19cm = 1.45m or 145cm
Yes it is. 19cm=190mm. 25mm=2.5cm.
If a circle has a diameter of 19cm the circumference is: 59.7 cm
