Answer:
12 cm
Step-by-step explanation:
width = x
length = x + 5
perimeter = 38cm
perimeter = length + width + length + width
x + 5 + x + x + 5 + x = 38
4x + 10 = 38
4x = 28
x = 7
length = x + 5 = 7 + 5 = 12
Length: 12 cm
2x + 2(x+5) = 38cm
2x + 2x + 10 = 38
4x = 38 - 10
x = 28/4
Length: 7+5=12cm
3
3(5^6)
8/10, 12/15, 16/20 and so on
4x2/5x2 = 8/104x3/5x3 = 12/154x4/5x4 = 16/20 and so on
432 square inches
thats the area, perimiter is 84 inches
