Answer 1

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
