Question

find the area and perimeter of a rectangle whose length is x+2 and breath is 2x.​

Answer 1

Answer:

GIVEN

LENGTH = X + 2

BREADTH = 2X

:.

PERIMETER OF RECTANGLE = 2(l + b)

2 ( x + 2 + 2x)

2 × 3X + 2

6X + 4

AREA

= L × B

X + 2 × 2X

= 2X² + 4X

Answer 2

Answer:

Area = 6x + 4

Perimetre = 2$x^{2}$ + 4x

Step-by-step explanation:

Area of the rectangle = 2(L + B)

                                    = 2(x + 2 + 2x)

                                    = 2(3x + 2)

                                    = 6x + 4

Perimetre of the Rectangle = L * B

                                             =  (x + 2) * 2x

                                             =  2$x^{2}$ + 4x
