1. a rectangle is 7 feet wide and 8 feet high; area =

56 ft²

Step-by-step explanation: To find the area of a rectangle, start with the formula for the area of a rectangle.

Area = length × width

Since the length of the rectangle is 7 feet and the width or height is 8 feet, we can plug this information into the formula to get (7 ft) (8 ft) which simplifies to 56 ft². Therefore, the area of the rectangle is 56 ft².

Fun Fact: Area can be defined as the space occupied by a flat shape or the surface of an object. The area of a figure is the number of unit squares that cover the surface of a closed figure.

Fun Fact: You can use area for cubic units, geometry, measurements, real world situations, and more!

To find Area, we must use a very important formula which is Area equals Length x Width. Notice that this isn't the formula for all area problems.

Our length is 8 feet high,

Our width is 7 feet wide.

Then we multiply both Length and Width.

7 times 8 = 56.

56 isn't our final answer, we must label and put square, (2), in our answer.

Our final answer is 56 ft².

Best of Luck to you!
