Question

Topic: Area of non shaded area.

PLEASE NO LINKS OR "Sorry i don't know this" or anything related to that.

Answer 1

150 Square Units

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=
`(1)/(2)bh`

b=base and h=height A=area

A=
`(1)/(2)(10)(15)`

A=
`(1)/(2)(10)(15)`=75

A=75

Multiply by two to get the area for both triangles.

75·2=150

Answer 2

Answer:B) 150

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
