8. Find the height of a triangle having an area of 1256 cm? and base is 31.4 cm About the author Evelyn
Step-by-step explanation: area of the triangle = b × h /2 = 1256 cm ² 31.4 cm × h / 2 = 1256 15 . 7 cm × h = 1256 h = 1256 /15.7 = 12560/157 which is equal to 80 cm height of the triangle = 80 cm Reply
Answer: Height = 31.4 cm Area = 1256 => Base × Height / 2 = 1256 => 31.4 ×Base = 1256 × 2 => Base = 1256×2 / 31.4 => Base = 40×2 => Base = 80 cm Reply
Step-by-step explanation:
area of the triangle = b × h /2 = 1256 cm ²
31.4 cm × h / 2 = 1256
15 . 7 cm × h = 1256
h = 1256 /15.7 = 12560/157 which is equal to 80 cm height of the triangle = 80 cm
Answer:
Height = 31.4 cm
Area = 1256
=> Base × Height / 2 = 1256
=> 31.4 ×Base = 1256 × 2
=> Base = 1256×2 / 31.4
=> Base = 40×2
=> Base = 80 cm
