Question

The length of a rectangle is 4cm more than the width and perimeter is at least 48cm. What are the smallest possible dimensions for the rectangle?

Answer 1

Answer:

length    = 14 cm

breadth  = 10 cm

Step-by-step explanation:

let,             length = (x + 4) cm

thus,        breadth = x cm

            perimeter = 48 cm      

perimeter of rectangle = 2( length+breadth )

                                48  =  2( x + x+4 )

                                 48 =  2( 2x + 4 )

                                 48 = 4x + 8

                            48 - 8 = 4x

                                40  = 4x

                            40 / 4 = x

                                10   = x

length    = x + 4 = 14 cm

breadth  =    x    = 10 cm
