Question

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.

Answer 1

Answer:

Width is 2 and Length is 6

Step-by-step explanation:

1. As the data is given, the area of a playground is 12 square yards.
2. The length of the playground is 3 times longer than its width.  
3. Let width is x, length is 3 times therefore, length = 3x

As we know the formula for area,

• Area=length x width.

So by putting values in this formula,

• 12sq = (3x)(x)  

=> 3x2 = 12

=> x2 = 12/3,

=> x2 = 4 ,

by taking square root we get x= 2,

• the width is 2 and length is 3 times hence, length is 3(2) = 6.
