Question

A rectangle is (x + 6) meters (m) long and (2x - 1) meters wide.

(x + 6) m
(2x - 1) m
Which expression represents the area of the rectangle in square meters?
O 2x2 - 6
020? + 7-6
O 2012 + 112 - 6
202 + 13x - 6

Answer 1

Option (3)

Explanation:

Length of the given rectangle = (x + 6) meters

Width of the given rectangle = (2x - 1) meters

Area of a rectangle = Length × Width

= (x + 6)(2x - 1)

= x(2x - 1) + 6(2x - 1)

= 2x² - x + 12x - 6

= (2x² + 11x - 6) square meters

Therefore, area of the given rectangle is defined by the expression given in option (3).
