The area of a rectangular plank is 4500 cm². the plank was broken into two pieces, one of which is a square and the other a rectangle. find the dimensions of the square if the length of the broken off rectangle is 120 cm.

30cm

Step-by-step explanation:

Let the dimensions of the square is x cm.

The plank of area 4500 cm² was broken into two pieces, one of which is a square and the other a rectangle.

Length of the broken off rectangle = 120 cm

Width of the broken off rectangle = x cm

Length of plank = (120+x) cm

Width of plank = x cm

Area of a rectangle is

Area of plank is

The area of a rectangular plank is 4500 cm².

Splitting the middle term we get

Using zero product property we get

x can not be a negative number because it is the side length of square. So, x=30.

Therefore, the side length of the square is 30cm.
