Question

In a parallelogram abcd,ab=12cm ae=7.5cm cf=15cm,then find ad

Answer 1

AB=12 cm

therefore CD=12 cm as AB=CD(opposite sides of a parallelogram are equal)

Area of parallelogram = base*height

= AE*CD

= 7.5*12

=90cm^2

Similarly area of parallelogram =base*height

90 =FC*AD

90 =15*AD

AD=90/15

AD=6 cm
