Perimeter of a triangle is the sum of the lengths of all the ............ sides.
The perimeter of a triangle is 6p2−4p+9 and the length of two of its adjacent side are p2−2p+1 and 3p2−5p+3. Find the length if the third side of the triangle. If p = 3, find the perimeter of the triangle. [4 MARKS]
Draw a triangle of perimeter 13 centimetres and lengths of sides in the ratio 2 : 3 : 4.
