Find the height and the area of rectangle if the perimeter is 38.4 inches and the base is 15 inches

1) 4.2 inches

2) 63 inches²

Step-by-step explanation:

If the base is 15 inches, we can assume that the opposite side is also 15 inches. 15 + 15 = 30. If we subtract 30 from the total perimeter, we will have the sum of the last two sides.

38.4 - 30 = 8.4

Now that we have the sum we can now find the exact length with division:

8.4/2 = 4.2 inches

To find the area, we multiply these together.

4.2 * 15 = 63
