The area of the quadrilateral shown is 252 square inches. What is the perimeter? (the width is 16.8 inches)

A. 61.8 inches
B. 31.8 inches
C. 63.6 inches
D. 67.2 inches

Answers

Answer 1

Answer:

Answer:

The answer is 63.6 $in^2$

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:

$A=a*b$

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:

$252=a*16.8\na=(252)/(16.8)\na=15$

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 $in^2$

Answer 2

Answer:

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

Which is greater 2 miles or 3 kilometers

Answers

2 miles = 3.21869 kilometers

3.21869 > 3

Answer: 2 miles is greater than 3 kilometers.

We already know that 1 mile= 1.60934 km.

2 miles* (1.60934 km/ 1 mile)= 3.21868 km > 3 km.

The final answer is 2 miles > 3 km~

Write an expression that can be used to multiply 6 times 198 mentally

Answers

I would half 198, get
99 and add a 0, this is how you multiply by 5 in your head

198*5 = 990
990 + 200 = 1190 - 2
= 1188

Alternatively we can round 198 to 200: then multiply by 6

200*6 = 1200

Then We subtract the 6 "2's" that we added

1200 - 12 = 1188

The expression for this is:
(6*200) - (6 * 2)
