An ecology center wants to set up an experimental garden using 400 meters of fencing to enclose a rectangular area of 9900 square meters. find the dimensions of the garden. (note that the fencing will be the perimeter of the garden, and the formula for the perimeter of a rectangle is p = 2l + 2w.)

Explanation:

Given that,

Fencing to be done, P = 400 m

Area of the rectangular garden,

Let l is the length and b is the breadth of the garden. The area of the rectangle is given by :

............(1)

The perimeter of the garden is given by :

...............(2)

On solving equation (1) and (2), we get the value of l and b are as follows :

l = 90 m and b = 110 m

or

b = 90 m and l = 110 m

So, the dimension of the garden is 90 m by 110 m. Hence, this is the required solution.

graph question answered .. you think better when you are relaxed and happy

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
