Calculate the shaded area

640

(I hope that I am right)

Step-by-step explanation:

The bigger shape :1. First, look at the triangle as a whole -

Area of a triange :

30 x 48 = 1440

1440 ÷ 2 = 720

2. Now let's look at the small triangle -

20 x 16 = 320

320 ÷ 2 = 160

The area of the bigger shape -720 - 160 = 560The smaller shape :1. Let's look at the shape as a rectangle first -

Area of a rectangle = Base x Height

20 x 16 = 320

2. Now let's do the little triangle -

20 - 30 = 10

10 x 16 = 160

160 ÷ 2 = 80

The area of the smaller shape -80The Area Of The Shaded Area :560 + 80 = 640

Yes the slope to this is -5
