A. 61.8 inches
B. 31.8 inches
C. 63.6 inches
D. 67.2 inches
Answer:
The answer is 63.6
Step-by-step explanation:
In order to determine the area of the quadrilateral, we have to know the values of its sides. The area of the quadrilateral is:
a= length of the quadrilateral
b=width of the quadrilateral
We know the area and the width of the quadrilateral, so we can determine its length:
Then, the perimeter of the quadrilateral is:
P=2*a+2*b
P=2*15+2*16.8
P=63.6
Finally, the perimeter is 63.6
C. 63.6 inches
That is because to find the length of the quadrilateral do this since you already know the width of the polygon:
252/16.8 = 15
Now that we know the length do this since this is the formula to find the perimeter or for me I would just 2x:
2(16.8) + 2(15) =
33.6 + 30 = 63.6
The perimeter of the quadrilateral is 63.6 inches
Answer:
7/50 meter.
Step-by-step explanation:
He has 7/8 meter. 1/5 of the piece of string is
.
Then, he uses 7/40 meter to tie a package. The rest of string will be
.
Then, the rest of string after he uses 1/5 is 7/10. Finally, he cuts the rest into 5 equal pieces, that is
.
Then, the lenght of each piece is 7/50 meter.
