The area of a playground is 12 square yards. the length of the playground is 3 times longer than its width. find the length and width of the playground.

Width is 2 and Length is 6

Step-by-step explanation:

As we know the formula for area,

So by putting values in this formula,

=> 3x2 = 12

=> x2 = 12/3,

=> x2 = 4 ,

by taking square root we get x= 2,

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
