13. Find the perimeter of a triangle that has legs that are 3 cm and 4 cm.
5 cm
7 cm
10 cm
12 cm

perimeter of a triangles are 12cm and 29cm respectively.

Step-by-step explanation:

finding the perimeter of a triangle simply means that you are finding the distance around. The simplest way to find the perimeter of a triangle is to sum up all its sides.

mathematically,

perimeter of a triangle = side A + side B + side C

perimeter of a triangle = 3cm + 4cm + 5cm

perimeter of a triangle = 12cm

for the second triangle according to the question

it says the triangle has sides, 7cm, 10cm, 12cm

perimeter of a triangle = 7cm + 10cm+ 12cm

perimeter of a triangle = 29cm

dc=6 square root of 3 and ac is 12 square root 3

c and d

step-by-step explanation:

square root of 3/2 = 18/c

cross multiply to get 18*2=√3*c

36/√3 * √3/√3 = c

c= 36*√3/3

c=12√3
