Answer:
Cilia
Step-by-step explanation:
Area = length x width
21 = length x 5
length = 21/5 = 4.2
The length is inversely proportional to the width because as the length increases the width reduces and vice-versa

➷ Work out the original area:
(5 x 18) / 2 = 45cm^2
Increase/decrease the changed values:
18 x 0.7 = 12.6
5 x 1.2 = 6
New area:
(12.6 x 6) / 2 = 37.8cm^2
Calculate percentage change:
((45 - 37.8) / 45) x 100 = 16
16% decrease
