Answer:

Height/Altitude is 24 centimeters

Base is 11 centimeters

Explanation:

$132=(bh)/(2)\\h=2b+2\\\\132=(b(2b+2))/(2)\\132=(2b^2+2b)/(2)\\132=b^2+b\\0=b^2+b-132\\0=(b+12)(b-11)\\b=11,-12$

Since the length of the base can't be negative, then the correct base would be 11 centimeters. This makes the altitude
h=2(11)+2=22+2=24 .
