Ok this is a hard problem of math you need to count the numbers form one through 100 and through 10 or 20 but keep it in oder
Answer:
1:5
so as the 25 is a multiple of. 5
Left side = 170-58 =121'
Bottom side = 96-4 =92'
Now let's calculate the upper oblique (slantwise) side by Pythagoras
oblique² = 92²+28² = 9248 & oblique =√9248 = 96.167'
The perimeter of the backyards = 96.167+93+92+121 = 402.167 ft
