whats the area and perimeter 4yd 5yd 3yd

Answer:Area = [tex]6 \ yd^2[/tex]; Perimeter = 12 ydStep-by-step explanation:Given:Sides given are 4yd, 5yd and 3 ydlet  a = 4yd b = 5yd and c = 3ydWe need to find Area and Perimeter.Perimeter can be found by adding all sidesPerimeter= sum of all sides = [tex]4yd+5yd+3yd = 12yd[/tex]Area can be found using Hero's formula which states;Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]where [tex]s= \frac{a+b+c}{2}=\frac{4+5+3}{2}=\frac{12}{2}=6yd[/tex]Substituting the values of s and sides we get area as;Area= [tex]\sqrt{6(6-4)(6-5)(6-3)}= \sqrt{6\times2\times1\times3}=\sqrt{3\times2\times2\times3}=3\times2 = 6yd^2[/tex]Hence, Area = [tex]6 \ yd^2[/tex]; Perimeter = 12 yd
