Use Structure A rectangular envelope has a clear window for the address to show. The measure of the envelope is 7 inches by 4 inches. The clear window is 4 inches by 1 inch. What is the area of the front of the nvelope not including the clear window?

To find the area of the front of the envelope not including the clear window, first calculate the area of the envelope itself. The area of the envelope is given by multiplying its length and width: Area of envelope = 7 inches * 4 inches = 28 square inches. Next, calculate the area of the clear window: Area of window = 4 inches * 1 inch = 4 square inches. Now, subtract the area of the window from the area of the envelope to find the area without the window: Area without window = 28 square inches - 4 square inches = 24 square inches. Therefore, the area of the front of the envelope not including the clear window is 24 square inches! Did you know that envelopes have been around since ancient times?
