Question

A triangle and parallelogram has the same base and the same area is the side of the triangle are 126cm 120 cm 130cm and parallelogram stand on the base 120cm find the corresponding right of the parallelogram

Answer 1

semi perimeter s of triangle = (126+120+130)/2 = 188 cm

Area of triangle = 
$\sqrt{188*(188-120)(188-126)(188-130)}=\\\\\sqrt{188*68*62*58}=8\sqrt{718301}$

Area of parallelogram = base*altitude 
$8\sqrt{718301}=120*altitude$

Altitude of parallelogram = 56.501 cm    aproximately
