Question

1. Estimate the area of the irregular shape. Explain your method and show your work? I don't know to to solve this.

Answer 1

I tried this:

Explanation:

I tried to consider simple shapes that can "fill" the given one as much as possible:

I got two trapeziums (one blue and the other red) and one triangle (red). the area of the trapezium is:

So:

`"Area"_("blue")=1/2(2+3)*5=12.5"u.a."`

`"Area"_("red")="trapezium"+"triangle"=1/2(4+2)*5+1/2(1*4)=17"u.a."`

We get:

`"Area"_("total")=12.5+17=29.5"u.a."`

[u.a. = unit of area]
