What is the area of the triangle ade in the following figure ?

Step-by-step explanation:

Hello

Area triangle DCE :

10 x (8/2) / 2 = 10 x 4 / 2 = 20 cm^2

Area triangle ABE = Area triangle DCE

Area ABCD :

10 x 8 = 80 cm^2

Area triangle AED :

Area ABCD - 2 area DCE

= 80 - 2 x 20

= 80 - 40

= 40 cm^2

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
