What is the area of a triangle with a hypotenuse of 21 and a leg of 16?
The hypotenuse of 21 does not yield an integral value for the second leg. The legs are 16 and the square root of 185, which is about 13.6 The area of the triangle is 1/2 (16 x 13.6) = about 108.8 212 = 162 + x2 x2 = 185 x = 13.6
What is the area of a triangle having dimensions of 29 cm by 21 cm by 20 cm showing work?
Let the sides of the triangle be abc and their opposite angles be ABC Angle C: (21^2 +20^2 -29^2)/(2*21*20) = 90 degrees by the cosine rule Area: 0.5*21*20*sin(90 degrees) = 210 square cm by the area sine rule Alternatively: 0.5*21*20 = 210 square cm because it is a right angle triangle
