The possible dimensions are -7 and -8 units.
Solution:
Area of the rectangular skateboard park =
To find the dimensions of the park.
Let us factor the polynomial:
15x can be written as 7x + 8x.
Take x common in 1st two terms and 8 common in next two terms.
Make sure that the remaining terms in the bracket should be equal.
Now, take the common term (x + 7) outside from both terms.
If the length of the park is -7 then the width is -8.
If the length of the park is -8 then the width is -7.
The possible dimensions are -7 and -8 units.
The area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
<h3>What is the area of the circle?</h3>
The area of the circle is the space occupied by it. It is the product of pi and square of its diameter divided by 4. The area of the circle can be given as,
Here (d) is the diameter of the circle. The diameter of the circle is 6 cm.
Put this value in the above formula to find the area of the circle as,
Thus, the area of the circle in pi units when the diameter of this circle is 6 centimeters is 9π centimeters.
