○=> Correct option :

Length of side of patio A = 12 yards

Area of patio A which is a square :

$=\tt side * side$

$=\tt 12 * 12$

$\color{plum} = \tt144 \: {yards}^(2)$

Thus, Area of patio A = 144 yards²

Length of side of patio B = 6.1 yards

Area of patio B which is a square :

$=\tt side * side$

$= \tt6.1 * 6.1$

$\color{plum} = \tt37.21 \: {yards}^(2)$

Length of side of the second patio B = 6.1 yards

Area of this patio :

$=\tt 6.1 * 6.1$

$\color{plum} = \tt37.21 \: yards$

Total area of Patio B :

= Area of first patio B + Area of second patio B

$=\tt 37.21 + 37.21$

$\color{plum} = \tt74.42 \: {yards}^(2)$

Thus :

▪︎Area of patio A = 144 yards²

▪︎Area of patio B = 74.42 yards²

▪︎Therefore, the correct option is (a) 74.42
