Explain the difference between area and perimeter. Choose one (area or perimeter) and write a word problem about it based on a shape you found in your surroundings. If possible, share a picture of the shape you found.
Perimeter is measured in linear units. It measures only one dimension to find the length of the object. It indicates the outline that surrounds a figure whereas area represents the space occupied by the object. It is measured in square units where only two dimensions are involved, length and width.
The area of a rectangular keyboard is 80 square units. If the length is 16 inches, then find the length.
area of a rectangle is length * width We plug in the values 80=16*w We divide 16 to both sides and get w=5. So the width would be 5 inches.
Area is the number of non-overlapping square units needed to exactly cover the entire side of the polygon, with "A" often representing it; I always remember the keyword, "inside". A = length (l) * width (w) or, A = base (b) * height (h)
Perimeter is the distance around a figure; I remember the keyword, "outside". P = 2l + 2w
My mirror is about 1 foot in length, and 4 feet in height. Find the area.
A = 1 * 4 = 4 ft P = 2(1) + 2(4) = 2 + 2(4) = 2 + 8 = 10 ft.
Area is the space within an enclosed space, such as a shape. Perimeter is the distance around an object.
My phone screen is 4.7 inches tall and 2.64 inches wide. To find the area, multiply the width times the height. 4.7 x 2.64 = 12.408 inches. Area= 12.408 inches squared.

P = 2(1) + 2(4)
= 2 + 2(4)

= 10 ft.
A= 4 ft.squared
P = 10 ft.squared
