Find the perimeter of a right angle triangle whose sides have sizes of 5 cm and 12 cm. |
30 cm 25 cm 17 cm 18 cm |
30 cm |
We know that, According to the pythagoras theorem = H2 = B2 + P2 Let B = 5 and P = 12 Then the H = H2 = 52 + 122 H2 = 25 + 144 = 169 H = \(\sqrt {169}\) = 13 So the perimeter of this triangle = 13 + 12 + 5 = 30cm |
