Answer:
10^3
Step-by-step explanation:
15-12=3
10^3
3t + 4s = $83
4t + 1s = $50 (x 4)
16t + 4s = $200
3t + 4s = $83 (minus them£
13t = $117 (divide by 13)
t = $9
sub t into first equation.
3 x 9 = 27
27 + 4s = $83
4s = $56
s = $14
t = $9
s = $14
42 because it is all of the sides have to be added up for the perimeter so the formula would be 14+14+7+7.
