Answer 1

Answer:

Hello mate ✌️

Step-by-step explanation:

Answer

A rectangle has all its angles = 90°

Thus, /_A = 90°

Now, E is midpoint of AD. Therefore;

AE = 1/2 × AD

AE = 1/2 × 40

AE = 20 cm

AB = 48 cm (Given)

By applying the Pythagoras Theorem in Triangle AEB:

=>

=>

=> EB = 52 cm

Answer 2

ANSWER

Given D and E are point on sides AB and AC respectively of triangle ABC such that  Area(ΔDBC) = Area(ΔEBC).

Given that  Area(ΔDBC) = Area(ΔEBC).

Then the height of triangle DBC and Triangle EBC are the same because both triangles are the same 

Then it possible that both triangle on the same base and between parallel line BC and DE 

Therefore, they will lie between the same parallel lines.

∴BC∥DE [henceproved]
