Question

# A ground in a shape of a parallelogram needs to be fenced by a wire. The one side of the parallelogram is 8 inches and the area of ground is 120 sq. inches respectively.

Find the minimum length of wire needed for the work.

Hint:

### ground is in the shape of parallelogram ,

The area of parallelogram can be given as where l and b are side lengths of

parallelogram where is the angle between l and b .

## The correct answer is: Min value of b = 15 inches

### Ans :- 15 m .

Explanation :-

Given ,

Area = 120 sq. inches

Min value of b = 15 inches to get minimum wire for fencing .

The figure above is the floor plan drawn by an architect for a small concert hall. The stage has depth 8 meters (m) and two walls each of

length 10 m. If the seating portion of the hall has an area of 180 square meters, what is the value of *x *?

**Note:**

There are different concepts used to solve this problem. Another concept used which is not mentioned in the hint is that the perpendicular drawn from the vertex of an isosceles triangle to the

base cuts the base in half. This property is also applicable in equilateral triangles as they are a special case of isosceles triangle.

The scatterplot above shows the revenue, in millions of dollars, that a company carned over several years and a line of best fit for the data. In Year 4 , the difference between the actual revenue and the predicted revenue is n million dollars, where is a posative integer. What is the value of n ? Round your answer to the nearest whole number. (Disregard the 5 sign when gridding your answer.)

**Note:**

As we are not certain if the point of the actual revenue is exactly at the midpoint of 50 and 60, so instead of taking the midpoint 55, we can also take it to be 54 or 56.

Then the value of *n* can be 4 or 6 too.
