Question

Find the area and perimeter of a rectangle with a length of 3x + 2 and a width of 4x + 3.

Answer 1

170ft^2

The area is 170ft^2.

Answer 2

Perimeter =14x+10

Area = =
`12x^(2)`+17x+6

Explanation:

Area of a rectangle=Length *width

=(3x+2)(4x+3)

=3x(4x+3)+2(4x+3)

=
`12x^(2)`+9x+8x+6

=
`12x^(2)`+17x+6

• Then find x using quadratic equation and substitute the values

Perimeter of a rectangle =2(length +width)

=2(3x+2+4x+3)

=6x+4+8x+6

=14x+10
