Answer:

12x² cm² and 27x² cm²

Step-by-step explanation:

Part A:

If the dimensions of the flax are (3x) cm and (4x) cm, then  the area is

A = L·W, or A = (3x cm)·(4x cm) = 12x^2 cm²

Part B:

If both length and width are now 1.5 times greater than before, our formula

A = L·W, or A = (3x cm)·(4x cm)

becomes:

A = L·W, or A = (1.5·3x cm)·(1.5·4x cm), or

                   A = (4.5x cm)(6.0x cm)  =  27x² cm²

The larger flag will have area 27x² cm²
