Question

the ratio of the lengths of the three sides of a triangle is 5:8:10. if the perimeter is 276 inches,find the length of the longest side of the triangle

Answer 1

ok

Perimeter = 276

Ratio = 5:8:10

1.- Sum up the numbers of the proportion

5 + 8 + 10 = 23

2.- Divide the perimeter by the previous result

276/23 = 12

3.- Calculate the length of the longest side

length = 12 x 10 = 120

4.- Result, the length of the longest side = 120 in
