Question

Triangle ADE is inside rectangle ABCD. Point E is half way between points B and C on the rectangle. Since AB is 8 cm and side AD is 7 cm.
1. what is the area of triangle ADE?
2. what is the ratio of the area of the triangle ABE to the area of triangle ADE?
3. What is the ratio of the area of the triangle CDE to the area of rectangle ABCD?
Thanks so much!!!

Answer 1

1. area = (1/2)(8)(7) = 28

2. triangle ABE : triangle ADE = 1 : 2

3. area CDE : rect ABCD = 1 : 4

Answer 2

thx so much!!!
