Question

The measures of two corresponding altitudes of two similar triangles are 6 m and 14 m. If the perimeter of the first triangle is 21 m, what is the number of meters in the perimeter of the second triangle?

Answer 1

we know that

perimeter second triangle=perimeter first triangle*scale factor

scale factor=measure second triangle/measure first triangle

scale factor=14/6

so

perimeter second triangle=21*14/6------>49 m

therefore

the answer is

the perimeter of the second triangle is 49 meters
