The perimeter of a rectangle is 53 inches. the length of the rectangle is 5 less than twice it’s width. solve the system using 2 equations.

length of rectangle=16 inches

width of rectangle=10.5 inches

Step-by-step explanation:

given ,perimeter of rectangle=53 inches

let ,length of rectangle= l=2b-5

  width of rectangle=b

p=2(l+b)

53=2(2b-5+b)

26.5=3b-5

31.5=3b

b=

b=10.5 inches

l=21-5=16 inches

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.
