Question

A rectangle has a height of 4 and a width of 2x^2-x express the area of the entire rectangle

Answer 1

Answer:

area of rectangle = l * b

let l= height

b= width

so , area of rectangle be h * w

4 * ( 2x^2 -x )

4x^2 - 4x cm^ 2

hope it correct or helpful

Answer 2

$\underline{\green{\bold{ Question : }}}$

A rectangle has a height of 4 and a width of 2x^2-x express the area of the entire rectangle

$\underline{\orange{\bold{ solution : }}}$

height : 4

width = 2x ^2 - x

= 2x² - x

= 2x × 2x - x

= 4x² - x

= 4x

rectangle is quadrilateral

area of quadrilateral = base × height

= 4x × 4

= 16x

$\boxed{\red{\bold{ area\: of\: quadrilateral = 16x }}}$
