Question

a rectangle has a base of 4x-1 and a length of 3x+2.what is the area

Answer 1

Answer:

hey mate here is your answer

area of rectangle = lxb

(4x-1)*(3x+2) = 12x^2 + 8x -3x -2

12x^2 + 5x -2

12x^2 + (8-3)x -2

12 x^2 + 8x -3x-2

4x(3x + 2) -1(3x+2)

x= -2/3

x= 1/4

Answer 2

Answer:

we know that area of rectangle = length× breadth

(4x-1)x(3x+2)

=12x2-3x+8x-2

=12x2+5x-2

now do factorise

you will get answer
