I hope this helps bc I don't know if I'm right or wrong but I still hope that it still works
It could be any fraction really. Some examples are 5/6, 7/9 or 12/24. It doesn’t really matter what the fraction ks
<u>Define x:</u>
Let the width be x.
width = x
Length = 4x
<u>Given the area, find Length and Width:</u>
The area is 100 cm²
Area = Length x Width
x(4x) = 100
Evaluate the Left Hand Side:
4x² = 100
Divide by 4:
x² = 25
Square root both sides:
x = 5
<u>Find the Width and the Length:</u>
Width = x = 5
Length = 4x = 4(5) = 20
<u>Find Perimeter:</u>
Perimeter = 2( 5 + 20) = 50 m
Answer: Perimeter = 50 m
1cm = 10cm
140cm=1400mm So Ben taller
Difference is bigger minus smaller
1400-1090=310mm :)
(=31cm)
