Area of a parallelogram = Base * Altitude
A = b * a
a = 2 * b
A = 288 cm.²
288 = b * a
288 = b * 2b
2b² = 288
b² = 144
[ Base = b = 12 cm. ]
a = 2 * b
a = 2 * 12
[ Altitude = a = 24 cm. ]
A = b * a
a = 2 * b
A = 288 cm.²
288 = b * a
288 = b * 2b
2b² = 288
b² = 144
[ Base = b = 12 cm. ]
a = 2 * b
a = 2 * 12
[ Altitude = a = 24 cm. ]

area of parallelogram=base ×height
288=b×2b
288=2b^2
288÷2=b^2
144=b^2
b=12
2b=2×12
=24
