Question

The hypotenuse and the base of triangle are 13 cm and 12 cm respectively find the area of triangle if its perimeter is 30 cm

Answer 1

ar of triangle is 1/2 *b * h
30 sq cm

Answer 2

hypotenuse=13cm
base=12cm
Perimeter of triangle=hypotenuse +base +perpendicular
30=13+12+perpendicular
perpendicular=30-25
                       =5cm
area of triangle=1/2*base*height
                         =1/2*12*5
                         =30cm2
