Question

find the perimeter of the parallelogram if it's area is 180​

Answer 1

don't know it's very difficult

Answer 2

Answer:

Step-by-step explanation:

In ||gm PQRS,

Let the height corresponding to side PQ be RT.

Now, length of RT is given as 36 cm.

Area of ||gm = bh

180 = PQ * RT

180 = PQ * 36

PQ = 5 cm

Again,

Area of ||gm = bh

180 = PS * RO

180 = PS * 40

PS = 4.5 cm

Now, perimeter of ||gm = PQ + QR + RS + PS

= PQ + PS + PQ + PS ( in || gm opp. Sides are equal)

= 5+4.5+5+4.5

= 19 cm

Therefore, perimeter of || gm PQRS is 19cm
