Answer 2

It is given that the length of the rectangle is three times of the breadth of rectangle.

Given,
Breadth of rectangle is 19 cm.


Hence,
Length of the rectangle = three times of 19 cm
Length of the rectangle = 3 x ( 19 cm )
Length of the rectangle = 57 cm



We know( formula ),
Area of rectangle = length x breadth


Therefore,
Area of this rectangle = 19 cm x 57 cm

Area of this rectangle = 1083 cm²


Therefore,
Area of the rectangle is 1083 cm², according to the given measurements.
