Answer:
The correct answer is option C. 21.25
Step-by-step explanation:
Formula:-
Area of triangle = bh/2
Where b - Base of triangle and h - Height of triangle
From the figure we can see a two isosceles triangle.
One triangle with base 5 m(2.5 + 2.5) and height 2.5 m
The second triangle with base 5 m and height 6
<u>To find the area of first triangle</u>
Here b = 5 m and h = 2.5 m
Area = bh/2 =(5 * 2.5)/2 = 6.25 m²
<u>To find the area of second triangle</u>
Here b = 5 m and h = 6 m
Area = bh/2 =(5 * 6)/2 = 15 m²
<u>To find total area </u>
Total area = Area of 1st triangle + area of 2nd triangle
= 6.25 + 15 = 21.25 m²
The correct answer is option C. 21.25
