A rectangle and a square are of equal area.If the lenght and the perimeter of a rectangle are 25cm and 58cm,then find the perimeter and area of the square.
Answers
Answer:
hope this helps you
Step-by-step explanation:
perimeter of rect. = 2(length x breadth)
58 = 2(25 x b)
58/2 = 25 x b
29/25 = b
or b = 1.16 cm
now area of the rect
length x breadth
25 x 1.16
29 cm²
It is given that the area of rect is equals to area of square
so, we can write
area of rect = area of sq
29 cm² = a²
or a = 5.4 cm
Answer ::
- The perimeter of square = 40cm.
- The area of square = 100cm².
Step-by-step explanation ::
To Find :-
- The perimeter of square
- The area of square
Solution :-
Given that,
- A rectangle and a square are of equal area.
- The lenght and the perimeter of a rectangle are 25cm and 58cm.
According the question,
First let's find out the breadth of rectangle,
⟾ 2 ( l + b ) = 58
⟾ 2 ( 25 + b ) = 58
⟾ 25 + b = 58/2
⟾ 25 + b = 29
⟾ b = 29 - 25
⟾ b = 4
Now, area of rectangle,
⟾ l × b = Area
⟾ 25 × 4
⟾ 100cm²
Therefore, the area of rectangle = Area of square = 100cm².
Now, let's find out the side of square,
⟾ Side² = Area
⟾ Side² = 100
⟾ Side = √ 100
⟾ Side = 10cm
Therefore, the perimeter of square is,
As we know that,
Perimeter of square = 4 × side
⟾ 4 × 10
⟾ 40cm
The perimeter of square is 40cm.
