A has coordinates (1,1) and B has coordinates (4,3). if AB is a side of a square, what is the area of the square?
kvasek [131]
Area of the square:
A = s²
and s = AB = sqrt ( ( 4 - 1 )² + ( 3 - 1 )² )
s = √ ( 9 + 4 ) = √ 13
A = ( √13 )² = 13

50 points and BRAINLIEST!
Harman [31]

Answer:

Step-by-step explanation:

The general equation of a circle is , x² + y² + 2gx + 2fy + c = 0

Substituting the three points we get the following equations,

2g +14f +c=-50

14g - 2f + c =-50

16g +12f + c = -100

Solving these equations we get,

g =-4, f = -3, c = 0

Hence general equation of circle is,

x² + y² - 8x - 6y  = 0

George would like to build a garden this year, George measure out his proposed garden and would like to know how many square fee
Blababa [14]

Answer:

The area is 105.5ft^2

Step-by-step explanation:

Required

The area of the composite figure

The figure can be divided to 2 shapes

(1) Rectangle: Length = 6ft and Width = 8ft

(2) Trapezoid: Height = 5ft (i.e. 8 - 3), Parallel sides = 9ft and 14ft (i.e. 20 - 6)

The area of the rectangle is:

Area = 6 * 8 = 48

The area of the trapezoid is:

Area = \frac{1}{2}(9 + 14) * 5

Area = \frac{1}{2}(23) * 5

Area = 11.5 * 5

Area = 57.5

So, the area of the garden is:

Total = 48 + 57.5

Total = 105.5
