Answer: 
Step-by-step explanation:
You know that the triangle ABC and the triangle DEF are similar.
Therefore, if the lenght of AC is 12 centimeters and the lenght of DF is 10 centimeters, then you can find the ratio as following:
Then, the calculte the length of EF, you must multiply the lenght BC of the triangle ABC by the ratio obtained above.
Therefore, the lenght EF is the following:
Answer:
Step-by-step explanation:
if you know that the perimeter is 20,
then you have to divide by 4 to get the length of one side
20/4=5.
Draw the diagonal and write in it's length as x.
Use Pythagorean formula
Then know that a2+b2=c2
and use the two side lengths as a and b.
This gives you the equation
5^2+5^2=x^2.
Do the calculations and solve the equation.
25+25=x^2
50=x^2
√50=x.
Therefore x=√50 where x equals the length of the diagonal.
Answer:
1275 yards
Step-by-step explanation:
- Find the area of the two triangles. To do that you multiply 15x13 to get 195 (this is the area of both of the triangles combined)
- Next, find the area of the three sides. To do this you multiply 24x15 to get 360 then multiply that by 3 because there is 3 sides. And you get 1080.
- Finally add the triangles and the sides 195+1080= 1275
