Answer:
78 cm should be the correct answer
Step-by-step explanation:
Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm
The perimeter is 38.4 inches
I don’t know if this is correct but about 4 times because
3/4 -> 18/24 and 1/6 -> 4/24
