Question

A rectangle doorway measures 90cm x 200cm. Weatherstripping is applied on the top and the 2 sides. Weatherstripping costs $6.00 per meter. What did it cost to weatherstrip the door?

Answer 1

90+90+200 = 380   380cm=about 3.8 meters. $6.00 times 3.8= about 18

ANSWER: about $18  

Answer 2

$29.40

Answer 3

Its around 17 bucks.

So try and figure it out.

Answer 4

so, you have to use a total of 490 cm of weather stripping for the door. 100 cm = 1 m, so you need 4.9 m. that would be $29.40. or if you have to buy full strips, you would need to buy 5, and that would be $30.

Answer 5

I'm looking at your other questions and your asking for help really bad you need to tell your teacher you don't understand this.

Answer 6

Length of top + 2 sidess = 90 + 2*200 = 490 cm = 4.9 m

Total cost = $6.00 per meter x 4.9 meter

= $29.40

Answer 7

.9 + 2 + 2 = 4.9m

4.9 x 6 = $29.40

Answer 8

100 cm = 1m.

top + 2 sides = 200 cm + 180 cm = 380 cm = 3.8 m

3.8m x $6 per m = $22.80

Answer 9

The total perimeter of the door is 90 + 90 + 200 + 200 = 580cm.

The perimeter that is weatherstripped is 90 + 200 + 200 = 490cm = 4.90 meters.

If weatherstrip costs $6 / meter and the amount needed is 4.9 meters, then the cost is 6 * 4.9 = $29.40
