Question

Find the exact perimeter of triangle ABC.

example; 4 √5+5 can be shown as; 4 times the square root of 5 + 5
Please write the answer like the example above

Answer 1

Perimeter of triangle ABC is
`6 √(5)+6` m.

Solution:

Given data:

AB =
`3 √(5)` m

BC =
`3 √(5)` m

CA = 6 m

Perimeter = Sum of all the sides

Perimeter of triangle ABC = AB + BC + CA

`=3 √(5)+3 √(5)+6`

`=6 √(5)+6` m

Perimeter of triangle ABC is
`6 √(5)+6` m.
