See attached for reference
<u>The points given:</u>
- (−6, −2), (0, −10), (5, 2), (−1, 10)
They form a rectangle as seen in the picture.
We can notice that this is a parallelogram, as respective lines have same difference of coordinates.
<u>So calculating only the two of the sides will be sufficient to get its perimeter:</u>
- a = √(-1+6)² + (10+2)² = √25+144 = √169= 13
- b = √(0+6)² + (-10+2)² = √36+64 = √100 = 10
<u>So, the perimeter:</u>
- P = 2(13+10) = 46

Answer:
x=2
Step-by-step explanation:
let x be the edge length of the square removed at each corner;
Hence the area of the base is:
Using the quadratic equation formula, or completing the square, x, or length of a side of one of the squares is x=2 or x=58
#Given that x=58 is larger than 40cm, the side length is x=2
