Answer:
4.5 cm x 6 cm
Step-by-step explanation:
Notice that the 150% enlargement can be written as a fraction:[tex]\frac{150}{100} = 1.5[/tex]
That gives us a clue about what value to multiply each side of the textbook by in order to obtain the new enlarged dimensions.
Therefore, the side which is 3 cm now becomes: [tex]3 cm * 1.5 = 4.5 cm[/tex]
and the side which is 4 cm now becomes: [tex]4 cm * 1.5 = 6 cm[/tex]
