Study the adjoining picture and answer the following questions:
The area of ΔABF is.
Answer & explanation
Correct answer: option 2
The correct answer is Option 2: 90 m2
From the figure:
-
The base BF = 10 m (horizontal distance from the vertical line through B to point F).
-
The height AB = 18 m.
The height is obtained from the diagram:
A to G = 12 m and G to B = 6 m, therefore
AB = 12 + 6 = 18 m
Using the triangle area formula:
Area of triangle
= 1/2 × base × height
Area of ΔABF
= 1/2 × 10 × 18
= 90 m²
