If all 3 sides are identical
Side A = 7p
Side B = q+10
Side C = 2p - 6q
So,
7p = 2p - 6q
5p = -6q
p = (-6/5)q
Side A = 7 * (-6/5)q = (-42/5)q
Side B = q + 10
(-42/5)q = (5/5)q + 10
(-47/5)q = 10
q = -50/47
p = (-6/5)(-50/47) = 60 / 47
So, p = 60/47 and q = -50/47
The perimeter = 7p + q+10 + 2p - 6q = 9p - 5q + 10
9(60/47) - 5( -50/7) + 10 = 540/47 + 250/47 + 470/47 = 1260/47
The perimeter is 1260/47
