The area of rectangle ABCD is 72 square inches. A diagonal of rectangle ABCD is 12 inches and the diagonal of rectangle EFGH is

luda_lava [24]

Answer:

The area of rectangle EFGH is $242\ in^{2}$

Step-by-step explanation:

For this problem I assume that rectangle ABCD and rectangle EFGH are similar

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

Let

z ------> the scale factor

The scale factor is the ratio between the diagonals of rectangles

so

$z=\frac{22}{12}=\frac{11}{6}$

step 2

Find the area of rectangle EFGH

we know that

If two figures are similar, then the ratio of its areas is the scale factor squared

Let

z------> the scale factor

x -----> area of rectangle EFGH

y ----> area of rectangle ABCD

so

$z^{2}=\frac{x}{y}$

we have

$z=\frac{11}{6}$

$y=72\ in^{2}$

substitute and solve for x

$(\frac{11}{6})^{2}=\frac{x}{72}$

$\frac{121}{36}=\frac{x}{72}$

$x=\frac{121}{36}(72)$

$x=242\ in^{2}$

Answer: 1 Ticket

Step-by-step explanation:

You need to find the number from the percentage

I do this by moving the decimals 2 spaces back (Divide by 100)

5%=0.05

Multiply the number of tickets sold by the new percentage number

20x0.05=1
