Question

In a rectangular plot of land 70 m long and 40 m broad, a circular garden of radius 17.5 m is developed. Find the cost of turfing the remaining portion at the rate of Rs 28.50 per sq. metre.​

Answer 1

Explanation:

area of plot =70×40

= 2800m^2

area of circular garden =πr^2

=22/7*17.5*17.5

=962.5 m^2

remaining portion =2800-962.5

= 1837.5m^2

cost = rate × area

= 28.50×1837.5

=₹ 52368.75

Question :-

What is photosynthesis?

____________________

Answer :-

The process by which green plants and some other organisms use sunlight to synthesize nutrients for their nourishment is called Photosynthesis.

Some requirements of photosynthesis to take place :-

Presence of carbon dioxide.

Presence of water.

In plants, in photosynthesis, require a green coloured pigment named 'Chlorophyll'.

Presence of Sunlight.

A temperature of 25°C to 40°C is needed.

Result ( product ) of photosynthesis :-

When the process of photosynthesis is completed, it releases Oxygen as a by-product.

Chemical Equation for Photosynthesis :-

$\sf6CO_2 + 6H_2O \binom{sunlight \: and \: chorophyll}{ \rightarrow} C_6H _ {12} {O _6 + 6O_2} \uparrow$
