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

Perimeter of triangle ABC is m.

Solution:

Given data:

AB = m

BC = m

CA = 6 m

Perimeter = Sum of all the sides

Perimeter of triangle ABC = AB + BC + CA

                                            m

Perimeter of triangle ABC is m.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
