Answer:
14 cm squared
Step-by-step explanation:
The shaded triangle is clearly half of the rectangle, and half of 28 is 14.
The other way you can look at it is that the dimensions of the rectangle are 4 cm and 7 cm. The area of a triangle equation is [tex]\frac{bh}{2}[/tex]. So [tex]\frac{4(7)}{2}[/tex] is 14.
