Answer:
1. a= 23.7 in, b= 10.7 in, c= 26 in
a²= 562 in², b²= 114 in², c²= 676 in²
2. a= 21.7 cm, b= 7.21 cm, c= 22.9 cm
a²= 473 cm², b²= 52 cm², c²= 525 cm²
3. a= 22 in, b= 12 in, c= 25.1 in
a²= 484 in², b²= 144 in², c²= 628 in²
4. a= 37.7 m, b= 16m, c= 41 m
a²= 1425 m², b²= 256 m², c²= 1681 m²

Inequation 1:
to plot the pairs (x, y) for which the inequation holds, draw the line
then pick a point in either side of the line. If that point is a solution of the inequation, than color that region of the line, if that point is not a solution, then color the other part of the line.
we do the same for the second inequation. Then the solution, is the region of the x-y axes colored in both cases.
inequation 2:
draw the lines
i) use points (0, -3), (3, -1)
ii)
use points ( 0, 4), (3, 2)
let's use the point P(3, 3) to see what region of the lines need to be coloured:
;
, not true so we color the region not containing this point
not true, so we color the region not containing the point (3, 3)
The graph representing the system of inequalities is the region colored both red and blue, with the blue line not dashed, and the red line dashed.
