If the side are increased by 45% then the area of green part will be 26.6955 [tex]mm^{2}[/tex].
Given that area of a shape of 37 [tex]mm^{2}[/tex] in which 60% is green.
We are required to find the area of green region if the side is increased by 45%.
Area is basically part of a surface covered by a shape.
When the side is increased by 45% then the area will increase by 45%*45%=20.25%.
Increased area =37*20.25%=7.4925
New area=37+7.4925
=44.4925
We have been given that 60% is the area of green.
Area of green region=44.4925*60/100
=26.6955 [tex]mm^{2}[/tex]
Hence if the sides are increased by 45% then the area of green part will be 26.6955 [tex]mm^{2}[/tex].
