Jack’s dog has run away three times. His parents decided to fence in the back yard. The backyard is a polygon 25 feet by 75 feet. How much fencing is needed?
i was thinking that you times the 2 numbers and got your answer but i dont think that would be rght

It should just be 25+25+75+75 as long as the fence will go around the entire backyard and there is nothing in the way.

25 + 25 + 75 + 75 = 200 feet

what you are doing is the area. you need the perimeter.
25+25+75+75= 50+150= 200
the anwer is 200 ft of fence

since they gave you two sides this implies the polygon is a quadrilateral, so you would need to find the perimeter which is 2*25+2*75 or 200 ft

If the yard is a rectangle, p=2l+2w=2*75+2*25=150+50=200'
If it is any other shape, we need more onfo.

x+2y= -8 2x-y= 4 from the 1st equation, x = -8 - 2y plug that into the 2d equation. 2x-y= 4 2(-8 - 2y) - y = 4 -sixteen - 4y - y = 4 -5y = 20 y = -4 plug that decrease back into an equation to discover x. 2x - y = 4 2x - (-4) = 4 2x + 4 = 4 2x = 0 x = 0 So, the given ordered pair (4, -2) isn't a answer to the device. the answer to the device is (0, -4).

you should divide it cause in between 25 and 75 there is by and by means divide so the answer is 3

If it's a rectangle you need to go all the way around. Draw a little sketch, label the sides, and 'walk it' with your pencil.
If you multiplied the width and length you'd get the area.

multiply the 2 numbers and then the answer, you need to multiply it 3 times because it says that jack ran 3 times
