Question

Area of B patios a.74.42. B.37.21. C.144

Answer 1

○=> Correct option :

$\color{hotpink}\tt\bold{(a)\ \: 74.42}$

○=> Steps to derive correct option :

Length of side of patio A = 12 yards

Area of patio A which is a square :

$=\tt side \times side$

$=\tt 12 \times 12$

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

Thus, Area of patio A = 144 yards²

Length of side of patio B = 6.1 yards

Area of patio B which is a square :

$=\tt side \times side$

$= \tt6.1 \times 6.1$

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

Length of side of the second patio B = 6.1 yards

Area of this patio :

$=\tt 6.1 \times 6.1$

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

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
