The base of a triangle is twice its height. if the area is 49 find the base and the height

The height of triangle is 7 units and base of triangle is 14 units

Solution:

The area of triangle is given by formula:

Where,

"b" is the base and "h" is the height of triangle

Given in question that,

Area = 49 square units

Also given that, base of a triangle is twice its height

Base of triangle = twice the height

b = 2h

Substituting the values in formula,

Since, height cannot be negative, ignore -7

The solution is h = 7

Substitute h = 7 in b = 2h

b = 2h

b = 2(7)

b = 14

Thus height of triangle is 7 units and base of triangle is 14 units

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
