Find the area of a parallelogram, whose base is (3x − 5y + 4) m and height is (x − 5y) m.
Given:
Base of the parallelogram = 3x - 5y + 4 meters
Height of the parallelogram = x - 5y meters
Formula Used:
Area of a parallelogram = Base × Height
Solution:
Area of parallelogram = (3x - 5y + 4)(x - 5y)
= 3x(x - 5y) - 5y(x - 5y) + 4(x - 5y)
= 3x2 - 15xy - 5xy + 25y2 + 4x - 20y
= 3x2 - 20xy + 25y2 + 4x - 20y m2
