Find the perimeter of the figure below. Notice that one side length is not given.
1 answer:
Answer:
48 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of its sides.
Find the length of the unknown side
Let the unknown length be x cm.
Notice that the sum of the lengths of the unknown side and the side measuring 5 cm I equal to the length of the side measuring 9 cm.
x +5= 9
<em>Subtracting 5 from both sides:</em>
x= 9 -5
x= 4
Add up the lengths of all of the sides to find the perimeter. I will add the lengths starting from the side measuring x cm (or 4 cm), and sum them up in a clockwise manner. This ensures that none of the sides are overlooked.
Perimeter of the figure
= 4 +15 +9 +7 +5 +8
= 48 cm

Explanation:
The question requires that we round the given number to Ten-thousand
To do so, we will have to write the place values of the numbers first
Next, we find the digits before the Ten-thousand digits and then approximate the value
One of the principles to use is that
numbers from 0 to 4 are rounded to 0
while numbers from 5 to 9 are rounded to 1
In our case, The thousand digit is 0, so we round down to 0, then we add to the Ten-thousand digits and convert each of the numbers before the Ten-thousand digits to 0
Thus, we will have
Hence, the answer is 1,370,000
