Question

10m 12m 4m7m 4m irregular figures

Answer 1

Notice that the figure resembles a rectangle with a missing rectangular section.

Since the length of the top part of the rectangle is 10m long, while the bottom lines are 4m each, then the combined length of those two parts is 8m. Then, the width of the missing rectangular section must be 2m long:

Then, to find the total area of the irregular figure, find the area of the greater rectangle and then substract the area of the small, missing rectangle.

The area of the greater rectangle is:

`10m*12m=120m^2`

The area of the smaller rectangle is:

`2m*7m=14m^2`

Then, the area of the irregular figure, is:

`120m^2-14m^2=106m^2`

Therefore, the area of the given figure is:

`106m^2`
