Question

Perimeter of a triangle is 32 cm. Lengths of its two sides are 7 cm and 13 cm. Find the length of its third side.​

Answer 1

Answer:12

Step-by-step explanation:

Perimeter of triangle is the sum of its three sides

13+7+x=32

20+x=32

x=12

Answer 2

Answer:

12cm

Step-by-step explanation:

perimeter of a triangle =32

length of two sides = 7 , 13

by Pythagoras theorem =a +b + c= perimeter of triangle

7 +13+x =32

20 +x=32

x=32- 20

x =12
