Mensuration Practice Test 4

Perimeter of the square = 12 cm, 24 cm
Each side of the square = $\frac{12}{4}$ = 3 cm, $\frac{24}{4}$ = 6 cm
Area of the smaller square = 3 × 3 = 9 $\mathit{c}{\mathit{m}}^2$
Area of the bigger square = 6 × 6 = 36 $\mathit{c}{\mathit{m}}^2$
Area of the bigger square is four times the area of smaller square.
