Question

find the area of parallelogram whose one diagonal is 6.8 cm and the perpendicular distance of this diagonal from the opposite vertex is 7.5 cm​

Answer 1

Answer:

Answer:

51 sq cm

Step-by-step explanation:

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 2

Step-by-step explanation:

area of the triangle formed when diagonal drawn is

1/2*7.5*6.8=25.5

area of parallelogram is 2*25.5=51
