Find the perimeter of the polygon with vertices at (1, , 3), (7, 7) and (4, 7)

So then the perimeter is just the sum of all of these lengths,

P= 6+4+3+5

Step-by-step explanation:

From (1,3) to (7,3) is 6 units.

From (7,3) to (7,7) is 4 units.

From (7,7) to (4,7) is 3 units.

You need to calculate the distance from (4,7) to (1,3)

Using the distance formula,

D² = (×1 - ×2)² + (y1 - y2)²

D² = (4 - 1)² + (7 - 3)²

D² = 9 + 16

D² = 25

D² = 5

answer

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
