Question

please solve my question of math​

Answer 1

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
