Answer:

Step-by-step explanation:

Firat triangle has a=4cm and b=a and P1=a*b/2=4*4/2=8cm^2

First parallelogram has h=4cm (from first triangle) and a=5.7cm

P2=a*h=22.8cm^2

Big triangle has h=4 and a=5.7+4=9.7

P3=a*h/2=9.7*4/2=19.4

And 4th triangle has the same are lik the first one, P4=8.

P=8+22.8+19.4+8=58.2cm^2

A thief steals a number of rare plants from a nursery. On the way out, the thief meets three security guards, one after anothe

<h3>What is arithmetic?</h3>

In mathematics, it deals with numbers of operations according to the statements.

Here,
Let the number of plants originally stolen by the thief be x.
On the way out, the thief meets three security guards, one after another. To each security guard, the thief is forced to give one-half of the plants that he still had, plus 2 more.

Here,
For gourd 1 the planet is given = 1/2 x
For gourd 2 the planet is given = 1/2 * 1/2 x = 1/4 x
For gourd 3 the planet is given = 1/2*1/4 x = 1/8 x
Total plant given to the gourds = 1/2x +1/4x +1/8x + 2 = 7/x/8x +2
Finally, the thief leaves the nursery with 10 plants
x - 7x/8 + 2 = 10
x/8 = 8
x = 64

Thus, the thief stole 64 plants.
