Four friends ram, mohan, ajay and sanjay are playing in a rectangular playground. ram suggested his friends to get the position by keeping a stone in the middle of the park and he told the stone is the origin for their position. now, they got the position of all four friends as (– 4, – 2), (– 3, – 5), (3, – 2) and (2, 3). mohan claimed that their position will form a quadrilateral if taken in order. ajay and sanjay are now trying to calculate the area of the quadrilateral formed by their position if taken in order. how much area they calculated.

The area calculated by them is 21.

Step-by-step explanation:

The given points are (-4,-2),(-3,-5),(3,-2) and (2,3).

The area of the quadrilateral:

A= .

From the given points,

A=

A=

A=

The area of the quadrilateral = 21.

The are is 28

Step-by-step explanation:

Given:

Point 1:  (– 4, – 2)

Point 2: (– 3, – 5)

Point 3: (3, – 2)  

Point 4: (2, 3)

then, the coordinates of the first point are x1 = -4, y1 = -2; of the second point x2 = -3, y2 = -5; and so on.

We can compute the area of the quadrilateral with the  shoelace formula as follows:

area = 1/2 * |x1*y2 + x2*y3 + x3*y4 + x4*y1 - x2*y1 - x3*y2 - x4*y3 - x1*y4 |

area = 1/2 * |(-4)*(-5) + (-3)*(-2) + 3*3 + 2*(-2) - (-3)*(-2) - 3*(-5) - 2*(-2) - (-4)*3 |

area = 1/2 * 56 = 28

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

you need to rotate this triangle about the origin 270 degrees clockwise to create the full square.
