The area of parallelogram whose diagonal is 6.8 cm and perpendicular distance of this diagonal from an opposite vertex is 7.5 cm is ?
we know diagonal divide parallelogram in to two congruent triangle and area of congruent triangle are equal
in other word we can say diagonal decide parallelogram in two equal are triangle
area of triangle =1/2 basex height
=1/2 x6.8x7.5 square cm
area of parallelogram will be equal to area of two triangle
area of parallelogram =2x1/2x6.8x7.5= 6.8x7.5 =51.00 square cm
Answer 51.00 square cm
