Answer:B) 150

Step-by-step explanation:

Area of rec= L×W

= 10×30= 300

Area of shaded area= 1/2 Base× Height

1/2×10×15=75

75×2 = 150

Area of unshaded part= 300-150= 150

Answer:

150 Square Units

Step-by-step explanation:

(Sorry if I become confusing)

The base of the triangles is 10 units.

The height of the triangles is 15 units.

The formula I used was A=[tex]\frac{1}{2}bh[/tex]

b=base and h=height A=area

A=[tex]\frac{1}{2}(10)(15)[/tex]

A=[tex]\frac{1}{2}(10)(15)[/tex]=75

A=75

Multiply by two to get the area for both triangles.

75·2=150
