The aspect ratio (length to width) of an lcd computer monitor is 5 : 4. the lcd monitor of a toshiba laptop computer has a perimeter of 32.4 inches. what is the diagonal measure of the screen? round to the nearest tenth of an inch.

Solution:

Formula of perimeter =

So, 2W + 2H = 32.4         ... (1)

Ratio = 5:4

So,

4W - 5H = 0         ... (2)

Solve equation (1) and (2).

W = 9.0 and H = 7.2

Use the Pythagorean theorem,

D = 11.52

D = 11.5

Hence, the measure of diagonal is 11.5 inches.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
