Question

The adjacent sides of a rectangle are
x² - 4xy + 7y² and x³ - 5xy. Find its area.
please don't reply if u don't know the answer TwT​

Answer 1

area of a rectangle= length× breadth

=( x^2-4xy+7y^2) (x^3-5xy)

=x^3(x^2-4xy+7y^2) -5xy(x^2-4xy+7y^2)

=x^5-4x^4y+7x^3 y^2 -5x^3 y +20x^2 y^2-35xy^3

i think its that's all
