you multiply 1.50 tmes 103 to get the rectangle width and 2.30 times 106 to get rectangle lenghth then multiply the width times length 1.50 x 103=154.5  2.30 x 106=243.8   243.8 * 154.5 = 37,667.1

I think you intend for those numbers "103" and "106" to be powers of ten ...  10³  and  10⁶ . So, if I am not barking up the wrong tree, the exercise goes like this: Width = 1.50 x 10³ cm Length = 2.30 x 10⁶ cm Area = (length) x (width) = (2.30 x 10⁶ cm) x (1.50 x 10³ cm)                                        = (2.30cm x 1.50cm) x (10⁶ x 10³)                                        =        3.45                x   10⁹   cm²                                        =         3.45 x 10⁵  m²
