    Area of rectangle = Length x Width

    √7 x (2√5 – √15)

    = 2√35 – √105 m²

    Hope it helps!

    Given :–

    A rectangle has length of √7 meters and width of ( 2√5 – √15 ) meters.

    To Find :–

    Area of rectangle.

    Formula to be Used :-

    \boxed{Area\:of\:rectangle=Length \times Width}

    Solution :–

    It is given that,

    Length = √7 meters

    Width = ( 2√5 – √15 ) meters

    Applying formula,

    Area = Length × Width

    Area = √7 × ( 2√5 – √15 ) sq. meters

    Area = ( 2√5 × √7 – √15 × √7 ) sq. meters

    Area = ( 2√( 5 × 7 ) – √( 15 × 7 ) ) sq. meters

    Area = ( 2√35 – √105 ) sq. meters

    Answer :–

    So, area of given rectangle is

    ( 2√35 – √105 ) sq. meters
