Question

a) What shape of the Pandal be chosen to minimize the expenses of using bulbs ? b) Suppose the Pandal chosen is to be divided into two equal triangular parts- one for displaying bamboo exhibits & another for displaying jute exhibits. How will you do it? c) Can you construct the panda chosen if adjacent sides are known? If yes , construct it with adjacent sides 8 cm & 5cm respectively. d) What is the cost of decorating the pandal, given that the adjacent sides are 22 m & 15 m respectively , and the cost of decorating 1 square metre area is Rs 525.​

Answer 1

Answer:

square

Step-by-step explanation:

because square is equal side long

Answer 2

Answer:

1. The shape of pandal should be chosen as a rectangle. Because it's perimeter is lesser than parallelogram and area is smaller than a square when both have same perimeter.
2. The pandal should be divided by any of the diagonals of the rectangular shape in case to divide into two equal triangular parts- one for displaying bamboo exhibits & another for displaying jute exhibits.
3. Yes, I can.
4. The cost of decorating the pandal is Rs. 173250.

Step-by-step explanation:

C.

Length of the pandal=8 cm

Breadth of the pandal= 5 cm

As there are two equal triangles,

Hypotaneous of each triangle

=$\sqrt{8^{2}+5^2}$ cm

=9.43398 cm

≈ 9.4 cm

So, perimeter of each triangle

=8+5+9.4 cm

=22.4 cm

Area of each triangle

=1/2×area×base    $cm^{2}$

=1/2×8×5  $cm^{2}$

=20 $cm^{2}$

Perimeter of the rectangular pandal

=2×(length + breadth) cm

=2×(8+5) cm

=26 cm

Area of the rectangular pandal

=8×5  $cm^{2}$

=40 $cm^{2}$

D.

When,

Given length=22 m

Given breadth=15 m

Area of the pandal

=length × breadth $m^{2}$

=20×15 $m^{2}$

=330 $m^{2}$

Cost of decorating 1 $m^{2}$ area is Rs. 525.​

So, Cost of decorating 330 $m^{2}$ area is Rs. (525× 330)⇒173250

The cost of decorating the pandal is Rs. 173250.
