Solution:
We have re-drawn the given diagram, as we can see the given rectangle is actually divided into two parts.
one is Large square and the other one is a smaller rectangle.
Now we will apply the Pythagoras theorem in the larger triangle which is inside the square.
So we can write

Now we will apply the Pythagoras theorem in the smaller triangle which is inside the smaller rectangle.
So we can write

The approximate sum of the lengths of the two sidewalks, shown as dotted lines
m
Hence the correct option is D

Answer:
$480
Step-by-step explanation:
10x12x4
<h2> <u><em>
answer: </em></u>21 is 70% of 30
</h2>
<h2><u><em>
Working out percentages
</em></u></h2><h2><u><em>
We have, 70% × x = 21
or, 70100 × x = 21
</em></u></h2><h2><u><em>
Multiplying both sides by 100 and dividing both sides by 70,
</em></u></h2><h2><u><em>
we have x = 21 × 100
70
x = 30
</em></u></h2><h2><u><em>
If you are using a calculator, simply enter 21×100÷70, which will give you the answer.</em></u></h2>
