Question

This is hard and I don't know how to do it! it is due today.

Answer 1

20

Explanation:

Times the height by the width

Answer 2

196m²

Explanation:

remove the area of ​​the missing triangle from the area of ​​the whole rectangle

Rectangle Area ( b*h) = 10 * 20 = 200m²

Right Triangle area (C1 * C2 : 2) 20-16=4=c1

10-8=2=c2

4*2:2=4m² (triangle area)

200 - 4 = 196m²

or you can solve with this expression:

10*20-[(20-16)*(10-8):2] =

196m²
