John road kids this drawing of a composite shape for an arc nest the area of the art drawing is 78 CM what is the height of the rectangle

10 centimeters
8 centimeters
12 centimeters
13 centimeters

To find the height of the rectangle, we first need to find the width of the rectangle. Since the area of the composite shape is 78 cm and the dimensions of the two squares are 6 cm x 6 cm each, the area of each square is 6 cm * 6 cm = 36 cm.

Therefore, the area of the rectangle is 78 cm - 2(36 cm) = 6 cm.

To find the height of the rectangle, we divide the area of the rectangle by the width:

6 cm / 6 cm = 1 cm

So, the height of the rectangle is 1 cm.
