1. a company builds wooden porches.

the porches are built in rectangular

shapes. how do the areas of the

porches change when the lengths

change?

the __ stays the same.

the lengths

the areas __ by __

square feet.

2. what if 2 feet were added to each width? explain

how the area of each porch would change.

d 25

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.

correct answer is b. 27/8
