Figure P total perimeter = 12 × length of square
Therefore, 12L = 360
1L = 360÷12
1L = 30
Figure Q
Total perimeter = 14 L
Total perimeter = 14 × 30
Total perimeter = 420 cm
Total area for Q = 7 square
Total area for Q = 7 × (30×30)
Total area for Q = 7 × 900
Total area for Q = 6300cm²
Hope this helps
