Answer 1

Answer:

462 square cm.

Step-by-step explanation:

$(42 \times 21) - (28 \times 15) \\ = 882 - 420 \\ =462$

Answer 2

Area of inner rectangle = l × b

A₁ = 28 × 15

A₁ = 420 cm²

Area of outer rectangle = l × b

A₂ = 42 × 21

A₂ = 882 cm²

Maximum possible area = A₂ - A₁ = 882 - 420

= 462 cm²
