find the perimeter of a rectangle whose length is 4cm greater than its height, and whose area is 60 cm^2.

32

Step-by-step explanation:

x=6

and it's x+x+(x+4)+(x+4)

80cm

Step-by-step explanation:

Lets have height be x

Then the length would be x+4

So the area would be x*x+4=60

Solve: 2x+4=60, 2x=36, x=18

The height is 18 so the length is 22

The perimeter=18*2+22*2

Result: 80cm

look a the sides they are perpendicular
