Question

class 7 question who know plzzz answer it ​

Answer 1

Answer:

a) Area of triangle= 1/2×B×H

Here base= AC= 12cm

Height= BD = 6cm

So, 1/2×B×H = 1/2×12×6= 36cm²

b) Area of triangle = 1/2×B×H

Here we take AB as Base

So, Base = AB=9cm

Height = CE = h cm

So, 1/2×B×H = 1/2×9×h

36= 4.5h

→h= 36/4.5=8cm.
