Answer:


(17 + 7 √(7) ) {m}^(2)

Explanation:

Area of a rectangle = Length × Width

Length given =
(3 + √(7) )m

Width given =
(1 + 2 √(7) )m

Area of the rectangle =


(3 + √(7) ) * (1 + 2 √(7) )


= > 3(1 + 2 √(7) ) + √(7) (1 + 2 √(7) )


= > 3 + 6 √(7) + √(7) + 2 * { (√(7) )}^(2)


= > 3 + 6 √(7) + √(7) + 2 * 7


= > 14 + 3 + 7 √(7)


= > (17 + 7 √(7) ) {m}^(2)
