Me asap which figure shows the conjecture is false? ? conjecture: a rectangle with an area of 12 square units must have a perimeter of at least 16 units

The easiest place to start is with the answer. The 3 by 4 rectangle (upper right) is the answer. P = 2(L + W) = 2(4 + 3) = 2*7 is 14.

14 is less than 16.

Now lets find out why the others can't be true.

The upper left has an area of 12 (6*2). So the area is find.

P = 2 * (L + W) = 2* (6 + 2) = 16 This would support the conjecture so it is not the answer you want.

The lower left has an area of 12 and a perimeter of 2*(12 + 1) = 26. That supports the conjecture. So you don't want that one either.

The lower right does not have an area of 12. It cannot help us at all.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
