Question

What is the ratio of the area of ABC to the area of ABD? Help me please

Answer 1

Area of Triangle ABC = 54
12 X 9 = 108
108 / 2 = 54

Area of Triangle ABD = 96
12 X 16 = 192
192 / 2 = 96

54 / 96 = 9 / 16

So the answer is B

Answer 2

What is the ratio of the area of ABC to the area of ABD? Help me please

Explanation:

The area of a triangle is equal to the Base x Height / 2.

ABC = 12 x 9 = 108/2 = 54

ABD = 12 x 16 = 192/2 = 96

54/96, divided by 6 = 9/16

The answer is: B. 9/16
