Answer:
54cm^2
Step-by-step explanation:
You need to calculate area of the given figure. To solve this there are two figures together, triangle and rectangle.
first find area of rectangle given length = 8 cm and breadth = 4cm
therefore area of rectangle = l * b = 8 * 4 = 32 cm^2
To find area of triangle:
The triangle itself is divided into two right angled triangle.
Now base of one right angled triangle will be 4/2 = 2cm
Area of rt. angled trangle = 1/2 * b*h = 1/2 * 2 * 11 = 11cm^2
Therefore area of whole triangle = 11*2 = 22cm^2 (since there are two rt.angled triangle)
Total area of given figure = 32 + 22 = 54 cm^2
