Question

Find the perimeter of the polygon.



perimeter:
ft

Answer 1

Perimeter = 22 feet

Explanation:

Perimeter is the outside measurement of the shape, and the sides are 4 and 7.

What you can do is add them together and multiply by 2, so

4+7 = 11

11*2 = 22

You can also just add all sides together

4 + 7 + 4 + 7 = 22

Answer 2

Given :

• »» Length of rectangle = 7 ft
• »» Breadth of rectangle = 4 ft

To Find :

• »» Perimeter of rectangle

Using Formula :

`{ \star{\small{\underline{\boxed{\sf{\red{P = 2(l + b)}}}}}}}`

• »» P = perimeter
• »» l = length
• »» b = breadth

Solution :

Here the given polygon is rectangle. So, finding the perimeter of rectangle :

`\begin{gathered} \qquad{\dashrightarrow{\small{\sf{P_((Rec)) = 2(l + b)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_((Rec)) = 2(7 + 4)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_((Rec)) = 2(11)}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_((Rec)) = 2 * 11}}}} \\ \\ \qquad{\dashrightarrow{\small{\sf{P_((Rec)) = 22 \: ft}}}} \\ \\ \qquad{\star{\small{\underline{\boxed{\sf{ \purple{P_((Rec)) = 22 \: ft}}}}}}}\end{gathered}`

Hence, the perimeter of the polygon is 22 ft.
