Step-by-step explanation:
Area of the border = area of the outer rectangle - area of inner rectangle
outer recangle L = 1.5 + (2×0.15) = 1.8 m
outer rectangle B = 1 + (2 × 0.15) = 1.3 m
inner rectangle L1 = 1.5 m
inner rectangle B1 = 1m
Area of border A = 1.8 × 1.3 - 1.5 × 1
=> A = 2.34 - 1.5
=> A = 0.84 m²
