a square and a rectangle have the same perimeter.the square has a side length of 8xunits.the rectangle has a length of 5x+8 and a width of 10 units .what will be the perimeter of both square and rectangle

Answer 1

perimeter of square = 4*8x=32x
Perimeter of rectangle = 2*(5x+8)+2*10=10x+16+20=10x+36
32x=10x+36
22x=36
x=36/22
P=4*8*36/22=2*8*36/11= 56.36 units
