Q.1 Find the perimeter using formula?.
Answers
Step-by-step explanation:
The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.
Answer:
The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle. The area of a two-dimensional figure describes the amount of surface the shape covers.
Step-by-step explanation:
Notice that the perimeter of a rectangle always has two pairs of equal length sides. In the above example you could have also written P = 2(3) + 2(8) = 6 + 16 = 22 cm. The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle.
Area of Parallelograms
The area of a two-dimensional figure describes the amount of surface the shape covers. You measure area in square units of a fixed size. Examples of square units of measure are square inches, square centimeters, or square miles. When finding the area of a polygon, you count how many squares of a certain size will cover the region inside the polygon.
Let’s look at a 4 x 4 square.
