By using the cosine rule in trigonometry the biggest angle works out as 106.23 degrees.
It is 106.2 degrees.
Using cosine rule largest angle is 106.23 degrees to two decimal places. Area of triangle: 0.5*8.5*9*sin(106.23) = 36.73 square cm to two decimal places.
It is impossible to get a triangle with the side lengths 14cm, 3cm and 8cm 14cm itself is larger than the sum of two other lengths (3cm + 8cm = 11cm).
A square with a side length of 14cm has an area of 196cm2
43.98 cm
SA = 1,176 cm2
There is no triangle with sides 14 cm, 3cm and 8cm. For a triangle to exist the sum of the two shorter sides must be longer than the remaining side. 3 cm + 8 cm = 11 cm < 14cm
3 times 14cm = a perimeter of 42cm
53.5 square cm to 1 d.p. Use the cosine rule to find an angle. Then use: Area = 1/2*a*b*sin C
Area is 98cm2

Type youre answer
The area of triangle is : 56.0
There is only one possibility in forming a triangle from the given dimensions and it is 4cm by 14cm by 16cm
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.
