Answer» -Equilateral triangle whose each side measures 6.4m ( take √3 = 1.73 in each case).To Find :-Area & height of the equilateral triangle. Solution :-As we KNOW that,Height of equilateral Δ = √3/2 × side [ Putting values ]↪ Height of equilateral Δ = √3/2 × 6.4↪ Height of equilateral Δ = √3 × 3.2↪ Height of equilateral Δ = 1.73 × 3.2↪ Height of equilateral Δ = 5.536 m.Now, we know that,Area of equilateral Δ = √3/4 × side²[ Putting values ]↪ Area of equilateral Δ = √3/4 × (6.4)²↪ Area of equilateral Δ = √3/4 × 40.96↪ Area of equilateral Δ = 1.73 × 10.24↪ Area of equilateral Δ = 17.71152 m².For information:Area of Δ = ¹/2 × base × height Area of SQUARE = (side)²Area of rectangle = Length × Base Area of rhombus = ¹/2 × d1 × d2Area of PARALLELOGRAM = Base × HeightArea of TRAPEZIUM = ¹/2 × (a + b) × h |
