23.8 inches squared if im wrong sorry but what i did was i added 7.4 plus 7.4 cause there are two of the same side then did the same with 4.5
3/5t -4 -7/10t = -2 (as you know 3/5 = 6/10) so
6/10t - 4 - 7/10t = -2
Simplify
-1/10t -4 = -2
add 4 to both sides
-1/10t - 4 + 4 = -2 + 4
-1/10t = 2
multiply -10 to both sides
-1/10t *(-10) = 2 * (-10)
Simplify
t = -20
Answer first one t = -20
