Find the width of a rectangle 25 feet and the perimeter is 80
2 answers:
The width of rectangle = 15 feet .
Step-by-step explanation:
<h2>Given = </h2>
- Perimeter of rectangle = 80
- Length of rectangle = 25 feet
<h2>To Find = </h2>
- width or Breadth of rectangle.
As we know ,
Perimeter of rectangle = 2× (L + B )
- where L is Length and B is width or Breadth.
Filling values in the formula :-
=> 80 = 2 ( 25 + B )
- we don't know the value of ' B' so we put ' B' as it is .
=> 80/2 = 25 + B
=> 40 = 25 + B
- when we combine like terms one side signs will be changed from + to - .
=> B = 40 - 25
=> B = 15 feet .

Properties of rectangle :
- It is a quadrilateral
- each angle is 90° .
- sum of angles is 360°
- Opposite sides are equal.
- Diagonals bisect each other.
Perimeter of rectangle = 2× L+B
Area = L×B .

- Given - <u>a </u><u>rectangle </u><u>with </u><u>length</u><u> </u><u>2</u><u>5</u><u> </u><u>feet </u><u>and </u><u>perimeter </u><u>8</u><u>0</u><u> </u><u>feet</u>
- To calculate - <u>width </u><u>of </u><u>the </u><u>rectangle</u>
We know that ,

where <u>b </u><u>=</u><u> </u><u>width </u><u>/</u><u> </u><u>breadth</u> of rectangle
