a piece of wire in shape of a circle with radius 14cm is bent to form a rectangle with sides (2y+20)cm long, (x+10)cm wide. given that the area of rectangle is 420 cm².find the values of x and y.

Sadie computes the perimeter of a rectangle by adding the length, l, and width, w, and doubling this sum. eric computes the perimeter of a rectangle by doubling the length, l, doubling the width, w, and adding the doubled amounts. write an equation for sadie’s way of calculating the
