Tatami mats are used as a floor covering in japan. One possible layout uses four identical rectangular mats and one square mat,
Maksim231197 [3]

a) Given

Total area = 81 feet squared.

 Let the area of the square mat = x feet.

From question, area of the rectangular mat is twice that of square mat.

 So, the area of the rectangular mat = 2 x feet.

Now,

Total area = 81 feet squared

Then,

      4(2 x) + x = 81\\ \\ 9 x = 81\\ \\  x = \frac{81}{9}\\ \\ x = 9\\

Hence  the area of the one rectangular mat = 2*9 = 18 feet squared

b) Let the width of the rectangular mat = y feet.

  Then length of the mat = 2 y feet.

   Area of the rectangle = 2 y* y = 2 y^{2}

   and area of rectangle = 18 feet squared.

   So,

 2 y^{2} = 18\\ y^{2} = 9\\ y= \pm3\\

Width can not be negative.

Hence, the width of the rectangular mat = 3 feet

and  length of the rectangular mat = 3*2 = 6 feet

azamat

Answer:

Step-by-step explanation:

hello :

h(x) = x² – 5x + 7

h(-2) = (-2)² – 5(-2) + 7 =4+10+7 =21

h(-5) = (-5)² – 5(-5) + 7= 25+25+7 =57

h(-8) = (-8)² – 5(-8) + 7 = 64+40+7=111
