The length of a rectangle is 3x + 6. The width of the rectangle is 4x + 2. Find the area and perimeter of the rectangle.
sladkih [1.3K]

Step-by-step explanation:

A= l × w

A= (3x+6)×(4x+2)

A= 12x²+6x+24x+12

A=12x²+30x+12

P=2l+2w

P=2(3x+6)+2(4x+2)

P=6x+12+8x+4

P=14x+16

Whitepunk [10]

Answer:

55.95 ft²

Step-by-step explanation:

Circumference formula:  C = 2πr  =>  r = C / (2π)

Area formula:  A = πr²

Substituting C / (2π) for r in the above equation, we get:

               C                        47 ft

A = π( ----------- )²  =  π ( -------------- )²

              2π                       (2π)

or ...

          π(47 ft)²                   2209 ft²

A = ----------------------  =  --------------------  =  55.95 ft²

               4π²                   4(3.14159)²
