Question

In the figure, ADCE is a parallelogram. Then area of ∆ECB equals

a) 21 m^2

b) 15.5 m^2

c) 3.5 m^2

d) 6.5 m^2

please answer this!!
​

Answer 1

Answer:

6.5m^2

Step-by-step explanation:

...this is very easy...

Answer 2

c) 3.5m² is the right option.

Since, ADCE is a paralleogram. So,

DC=AE=5m.

EB=AB-AE

EB= 7m-5m=2m.

Area of ∆ECB

=1/2×BASE× HEIGHT

=1/2×2×3.5

=> 3.5m².

Hence, (c) option is right!!✔✔
