The figures shows the show the dimension of a tennis court and a basketball court given in term of the width x in feet.

------------------------------------------------------------------------------
Formula
------------------------------------------------------------------------------
Perimeter = 2(Length + Width)

------------------------------------------------------------------------------
Perimeter of the Tennis Court
------------------------------------------------------------------------------
Perimeter of the Tennis Court = 2(Length + Width)
Perimeter of the Tennis Court = 2 (2x + 6 + x)
Perimeter of the Tennis Court = 2 (3x + 6)
Perimeter of the Tennis Court = 6x + 12

------------------------------------------------------------------------------
Perimeter of the Basketball Court
------------------------------------------------------------------------------
Perimeter of the Basketball Court = 2(Length + Width)
Perimeter of the Basketball Court =
Perimeter of the Basketball Court =
Perimeter of the Basketball Court =

------------------------------------------------------------------------------
Tennis Court = 6x + 12 ; Basketball Court = 7x + 36
------------------------------------------------------------------------------

------------------------------------------------------------------------------
Difference in the two perimeter
------------------------------------------------------------------------------
(7x + 36) - (6x + 12)
= 7x + 36 - 6x - 12
= x + 24

------------------------------------------------------------------------------
Basketball Court is (x + 24) unit greater than Tennis Court
------------------------------------------------------------------------------

------------------------------------------------------------------------------
Tennis Court is 36 feet wide. Find dimension
------------------------------------------------------------------------------
Width of Tennis Court = x = 36 ft
Length of Tennis Court = 2x + 6 = 2(36) + 6 = 78 ft
Perimeter of Tennis Court = 6x + 12 = 6(36) + 12 = 228 ft

Width of Basketball Court = 1/2x + 32 = 1/2(36) + 32 = 50 ft
Length of Basketball Court = 3x - 14 = 3(36) - 14 = 94 ft
Perimeter of Basketball Court = 7x + 36 = 7(36) + 36 = 288 ft

------------------------------------------------------------------------------

Tennis Court is 36 ft by78 ft and its perimeter is 228 ft.
Basketball Court is 50 ft by 94 ft and its perimeter is 288 ft

She should use 12/3 to measure

One shot. if 60% of 10 is 6, then what is 70%? we know it would be seven (since 60% is mathematically 60/100, or 6/10, then 70% is 70/100, or 7/10) but we can check anyway using ratios: 6 : 60% = x : 70%*inverse multiplicationx * 60% = 6 * 70%*divide both sides by 60%x = (6 * 70%) / 60%x = 7and since he has made 6 shots already, he would need just one more to get 7 shots or 70%. if the explanation is too confusing, comment and i will try to
