Find the area of rectangle b c e f​

Mathematics
1 answer:
Xelga [282]4 years ago
8 0

Answer:

Area is 16

Step-by-step explanation:

To obtain the area of the shown rectangle we need to obtain the dimensions of its sides.

Since all we have are coordinates, we need to apply the equation for distance between points.

That is

d=\sqrt{(x_{2}-x_{1})^2 +(y_{2}-y_{1})^2  }

To obtain BF.

(x2,y2)=(0,3)

(x1,y1)=(-2,1)

BF=SQRT(4+4)=SQRT(8)=2 sqrt(2)

To obtain BC

(x2,y2)=(4,-1)

(x1,y1)=(0,3)

BC=SQRT(16+16)=SQRT(32)=4 SQRT(2)

The area of the rectangle B C E F is the product BC*BF= (2*sqrt(2) * 4*sqrt(2))=(8*sqrt(2)*sqrt(2))=8*2=16

How do you solve this problem? I need help
Gnoma [55]
Check the picture below.

notice the bottom part of the picture, just using the tangent of the angle, we can get the angle itself, and you'd know what "x" and "y" are from the above part.

how much farther would they have to walk up? well, the hypotenuse of the longer triangle is "h", the hypotenuse of the shorter triangle is 122, so, they'd have to walk " h - 122 " more.

socks cost $2 per pair. the cost of n pairs $2n. john says that the cost of 6 pairs is $26 and the cost of 7 pairs is $27. is th
just olya [345]

Answer:

John is incorrect. He did not multiply.

Step-by-step explanation:

If a pair of socks cost $2, then the total cost of the socks if you buy n pairs is $2n. In the expression 2n, the 2 is the dollar amount and the n is the number of pairs.

1 pair is $2.

2 pair are $4.

3 pair are $6.

4 pair are $8.

5 pair are $10.

6 pair are $12.

7 pair are $14.

13 pair are $26.

There is no way to spend $27 on these socks.

25 pair are $50.

Hopefully, you can use logic, your prior knowledge of making purchases of multiple items and also algebra to see you must multiply the number of items you're buying times the cost per item.

6 pair are $12 and 7 pair are $14. John is wrong. He did not multiply.
