Answer:

157 inches squared

Step-by-step explanation:

Divide the figure into smaller figures (see image for one way):

Then, find the area of each figure. In my example:

= (4x5)+(5x12)+(11x7)

= 20+60+77

= 80+77

= 157 inches squared

VMariaS [17]

$dvd=d \\ cd=c \\ \\ \left \{ {{d=2c} \atop {2d+2c=45}} \right. \\ \\ 2(2c)+2c=45 \\ 4c+2c=45 \\ 6c=45 \\ c=7.5 \\ \\ d=2(7.5) \\ d=15$

One CD costs $7.50.
One DVD costs $15.00.

The width of a rectangler figure is 5 units smaller than its length. if its area is 14 units square. find its dimensions

oksano4ka [1.4K]

W = L - 5

A = W.L

14 = (L - 5).L

14 = L² - 5L

L² - 5L -14 =0

(L - 7)(L + 2) = 0 {factorized}

L = 7 / L = -2

In this case L would be equal to 7 because a length of anything can't be a negative number

Therefore, W = 2

Answer : Length = 7 Width = 2
