1) a square has an area of 36 ft2. what is the perimeter of the square?
2) a circle has a circumference of 16 pie (3.14). what is the area of the circle?

1) 24 feet

Step-by-step explanation:

1) area of a square=a^2

perimeter= 4*a

area=36ft^2=a^2

a=

a=6 feet

perimeter of the square= 4*6=24 feet

man its nopq i just guessed and got it right so uhh

g00d lucc

step-by-step explanation:

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.
