Question

Find the area of the figure. All angles are right angles

Answer 1

Looking at the figure, train your mind that this is a square (Square leads to a full 360)
Next after you times 18x20=360
Look at the bottom of the figure notice that it still adds up to 20 but a chunk was removed, we need o find the new area of the figure due to this missing chunk. How?
We have a height of the two legs of the figure 5 the base is also 5
So with some calculator magic you get 25 for both legs
Still with me? Good.
LOOK its 10 on the base of both legs and in between the legs lays another 10! (From the top of the figure which is complete it was 20)
So theres your 20 but wait WAIT!
If you go back you got the area of the two legs which were 25 x2 you get 50 thats a missing chunk there so take away 50 from 360 whats your answer????

Answer 2

`310\text{ m}^2`

Explanation:

We have been given a figure and we are asked to find the area of our given figure.

As all angles are right angles, so to find the area of our given figure we will subtract the area of smaller rectangle (10 m by 5 m) from the area of bigger rectangle (20 m by 18 m).

`\text{Area of the figure}=(20\text{ m}* 18\text{ m})-(10\text{ m}* 5\text{ m})`

`\text{Area of the figure}=360 \text{ m}^2-50\text{ m}^2`

`\text{Area of the figure}=310\text{ m}^2`

Therefore, the area of our given figure is 310 square meters.
