Answer:
x=14 y=-3
Step-by-step explanation:
Answer:
A = 1/2(y2-y1) (x3-x1)
A = 21 units^2
Step-by-step explanation:
The area of a triangle is 1/2 bh
Using the left side as the base b= 6 units
This is found by taking (y2-y1)
The height is 7 units, counting from the left side to x3
This is found by taking (x3-x1)
A = 1/2(y2-y1) (x3-x1)
A = 1/2 (6*7)
A = 1/2 *42
A = 21 units^2
Perimeter is the sum of all 4 walls.
Divide the perimeter in half for the total of the width + the length:
26/2 = 13 meters
Subtract the difference in length:
13 - 3 = 10
Divide by 2 walls:
10/2 = 5
The width is 5 metes.
The length is the 5 metes + the 3 meter difference = 5 +3 = 8 meters.
The length is 8 meters and the width is 5 meters.
