Answer:

$1120 more.

Step-by-step explanation:

14 x 10 = 140

140 x $40 = $5600

10 + 2 = 12

14 x 12 = 168

168 x $40 = $6720

$6720 - $5600 = $1120

Answer:

$1120 more

Step-by-step explanation:

Given length = 14 feet

          breadth = 10 feet

Therefore, area of the sun room is = length x breadth

                                                         = 14 x 10

                                                         = 140 square foot

Cost of one square foot = $40

∴ Cost of 140 square foot is = 140 x 40 = $5600

Now when the width is increased to 12 feet.

New area of the  sun room is = length x breadth

                                                         = 14 x 12

                                                         = 168 square foot

We know,  Cost of one square foot = $40

∴ Cost of 140 square foot is = 140 x 40 = $6720

Therefore increased cost is $ ( 6720 - 5600 )

                                           = $ 1120
