Question

1) The heights of ∆ABC and ∆DBC are 3cm and 4cm respectively. Find A(∆ABC):A(∆DBC).​

Answer 1

Answer:

3/2 : 2/1 =  1.5 : 2

Step-by-step explanation:

height of triangle ABC is 3 cm

                             DBC is 4 cm

area of triangle ABC = 1/2 x height x base

                                  =  1/2 x 3 x base

                                  = 3/2 x base

area of triangle DBC = 1/2 x 4 x base

                                   = 4/2 x base

                                    = 2 x base

therefore ratio is

3/2 x base : 4/2 x base

         3/2   : 4/2

          3/2  :  2/1

            1.5 : 2
