Question

Which of the following expressions could be used to find the area of the larger rectangle?

3(64 mm squared)
9(64 mm squared)
9(32mm squared)
3(576mm squared)

1 is 12 mm wide and 48 mm long and the other is 4mm wide and 16 mm long

Answer 1

we have
smaller rectangle dimensions
4 mm x 16 mm

larger rectangle dimensions
12 mm x 48 mm

[area of larger rectangle]=12*48-------> (2²*3)*(2^4*3)----> 3²*2^6---> (9*64) mm²

the answer is
9(64 mm squared)
