Question

A rectangle has a height of 2 and a width of 5x^2-2x+3 express the area of the entire rectangle

Answer 1

Answer:

Area=l×b

$= 5x {}^{2} - 2x + 3 \times 2$

=

$10 {x }^{2} - 4x + 6$

is the area of the rectangle

Answer 2

Given,

Height  = 2

Width = $5x^2-2x+3$

To Find,

Area of the entire rectangle =?

Solution,

From the formula for the area of a rectangle, we know

Area of the rectangle  = Height * Width

Area of the rectangle  = $2 *(5x^2-2x+3)$

Area of the rectangle  = $(2 *5x^2)- (2 * 2x)+ (2 *3)$

Area of the rectangle  = $(10x^2)- (4x)+ (6)$

Area of the rectangle  = $10x^2- 4x+ 6$

Hence, the area of the entire rectangle is $10x^2- 4x+ 6$
