Answer:
20.5cm^2
Explanation:
The area of the rectangle on the bottom is:
Area = length×width
= 8 × 1
= 8 cm^2
The triangle on top has a height of 5 and base of 5. The area of the triangle:
Area = 1/2 base•ht
= 1/2 (5)(5)
= 12.5 cm^2
Add the area of the triangle and the rectangle.
Area_total
= 8 + 12.5
= 20.5cm^2
