The perimeter is given by :
4 * √[9^2 + 6^2 ] =
4 √117 ft.
Here is what Melody is describing....it's known as the "complex" plane....

Very impressive, silver27.....!!!!!
3 points from me....
The length of the longer diagonal will be given by :
2 * √[51^2 - 24^2]
Just set each equation equal to its opposite side and solve......!!!!
A1 is 5cm on a side and A2 is 7cm on a side......
So ... A3 = 5 x 7 = 35 sq cm
(0, -7)
(2, -1)
(5, 8)
(6, 11)
The slope between succssive points is 3
The y intercept is -7
So....the rule is:
y = 3x - 7
$4635.21(1+.08/12)^12*5 = $ 25099.65
Area of ABC = (1/2)(BC)(AD) =
(1/2)(3.5 )(3.5) ≈ 6.125 sq cm
Here's a pic.......
1/3*pi*2^2*sqrt(10^2-2^2) =
(1/3) * pi * 4 * √[100 - 4 ] =
(1/3) * pi * 4 * √[96] =
(1/3) * pi * 4 * 4 √6 =
(16/3) * pi * √6 =
about .... 41.042
