A parallelogram has a circumference of 36 cm. The heights of the two adjacent sides are 4.8 cm and 6 cm. How long are the two sides?

A parallelogram has a circumference of 36 cm. The heights of the two adjacent sides are 4.8 cm and 6 cm. How long are the two sides?


Let two adjacent edges be a and B respectively
According to the meaning of the title
2(a+b)=36
4.8a=6b
Simplification
a+b=18(1)
a=5/4b(2)
(2) Substituting (1)
5b/4+b=18
9b=18×4
B = 8 cm
A = 18-8 = 10 cm
Or: the sum of two adjacent sides is 36 / 2 = 18 cm
Let one edge be a cm and the other 18-a cm
4.8a=6×(18-a)
A = 10 cm
The other one is 18-10 = 8 cm



The perimeter of a parallelogram is 24 cm, and the difference between a group of adjacent sides is 1 cm. What are its respective lengths


Parallelogram opposite sides equal 24 △ 2 = 12 (a group of adjacent sides and) (12 + 1) △ 2 = 6.5 6.5-1 = 5.5
