The perimeter of a parallelogram is 150 cm. One of its side is greater than the other by 25 cm.
Find length of all sides of the parallelogram.
Answers
Answer:
Step-by-step explanation:
perimeter of parallelogram=2(a+b)
let one side=x cm.
so other side=(x+25)cm.
perimeter=150cm.
150=2{X+(X+25)}
150=2(2X+25)
150=4X+50
150-50=4X
or 4X=100
X=25
so sides are:
25 and 50 cms.
Solution :-
First of all we need to know that what is parallelogram ?
» Parallelogram is a quadrilateral in which opposite sides are parallel to each other .
Let us see some Properties of Parallelogram :-
▪️ Opposite sides are congruent to each other i.e they have same length.
▪️ Opposite angles are congruent to each other .
▪️ Diagonals bisect each other .
▪️ Each of the Diagonals divide the parallelogram into two congruent triangle.
Now solving the problem :-
Given that
Perimeter = 150 cm
One side is greater than other by 25 cm
Now let the smaller side be x cm
Then other side = (x + 25) cm
Now from the property of the parallelogram :-
Opposite sides are equal
→ Two of the sides = 2x
→ Two of the sides = 2(x + 25)
Now by solving it further
→ 2x + 2(x + 25) = 150
→ 2x + 2x + 50 = 150
→ 4x = 150 - 50
→ 4x = 100
→ x = 25 cm
and other side = x + 25
= 50 cm
