Answer 1

Answer:

let the sides of triangle are = 4x, 7x, 5x.

acc. to que. 4x+7x+5x=128 yards

16x=128

x=8

longest side will be 7x

7×8=56 yards

Answer 2

Answer:

let the sides be 4x,7x&5x

perimeter of triangle =128

4x+7x+5x=128

16x=128

x=128/16

x=8

side = 4x=4×8=24

7x=7×8=56

5x=5×8=40

so the longest side is 56
