Consider a right angle triangle where the length of the shorter leg is one third of the length of its hypotenuse. If the length of the shorter leg is 7 cm,

then calculate the area of thetriangle in square cm.


Length of shorter leg is 7cm Length of hypotenuse is 3×7=21cm Length of longer leg is square root of (21×21 - 7×7)= 19.8cm ( By pythagauras theorem) area of triangle=base × height /2 = 7× 19.8/2 = 16.29 Square cm
