Try this option:
note, that distance between the parallel sides is shown via formula of area.
If it is possible, check the arithmetic.
The Area of the platform is 33m²
Step-by-step explanation:
As the question says, the height of vertex from the base (D from AB) is 7m whereas the height of left vertex from the base (E from AB) is 4m
Thus it means the height of the Δ DCE (DX)= 7-4 ⇒3m
Since the platform is five-sided, the figure can be broken down into constituting parts
- Parallelogram ║ABCE
- Δ DCE
Are of the figure= Area of ║ABCE+ area Δ DCE
Area of ║ABCE= breadth * height
= 6*4 ⇒24m
²
Area Δ DCE= ½*(base)(height)
Putting the value of base is 6m and height as 3m
Area Δ DCE= ½*6*3
=9m
²
Total area= 24+9= 33m

Answer:
The area of the triangle is of 8 units of area.
Step-by-step explanation:
Answer:
The area of the triangle is of 21 units of area.
Step-by-step explanation:
The area of a triangle with three vertices 
is given by the determinant of the following matrix:
In this question:
Vertices (1,0) (5,0) (3,4). So
The area of the triangle is of 8 units of area.
Answer: y = 1/2x - 9
Step-by-step explanation:
- y + 5 = 1/2(x - 8)
- y + 5 = 1/2x - 4 (distribute)
- y = 1/2x - 9 (subtract 5 from both sides)
