Step-by-step explanation:
Let base be x cm , then altitude will be (x-7) cm.
Now ,
By using pythagoras theorem-
132 = x2 + (x-7)2
169 = x2 + x2 + 49 - 14x
2x2 - 14x - 120 = 0
x2 - 7x - 60 = 0
x2 - 12x + 5x - 60 = 0
x ( x - 12 ) + 5 ( x - 12 ) = 0
Hence x = 12
sO , Altitude is 5 cm
AND. ,
base = 12cm
