I think its 72 cause 8x3 is 24. and then 24x3 is 72.. let me kniw if im right!
A circle has an infinite number of lines of symmetry.
Back yard- 24.5 x 18= 442
Front yard- 18.5 x 14.5 = 268.25
Other " - 12.5 x 14.5 = 181.25
Total = 890.5 sq ft
Y = -2x + 3
Slope is -2......and when x = 0 thats the y intercept.
