Question

The scale factor for two similar rectangles is 3. If the area of the smaller one is 8m^2, what is the area of the larger rectangle

Answer 1

A=lw
bigger one is
A'=(3l)(3W) or
A'=9lw

so the bigger one is 9 time of smaller

8*9=72
larger is 72m^2

Answer 2

The length of the smaller rectangle at the right is 1 inch less than twice its width. Both the dimensions of the larger rectangle are 2 inches longer than the smaller rectangle.
