find the area of a right angle triangle whose base is 12, Area, General Mathematics

Question:Find the area of a right angle triangle whose base is 12 cm and hypotenuse 13 cm.

Answer Height of the triangle` = sqrt((13))^2 - (12)^2`

            `= sqrt(25) = 5 cm.`

:. Its area` = 1/2 xx Base xx Height`

      `= ( 1/2 xx 12 xx 5) cm^2`

      `= 30  cm^2`
