The height of a triangle is 1 cm less than twice the length of the base. let x = the length of the base. write a function rule for the area of the triangle and determine the area if the length of its base is 16 cm.

a. a=12x(2x−1); 248cm2
b. a=12xh; 128cm2
c. a=12x(x−2); 112cm2
d. a=122x(x−1); 240cm2

The function rule for the Area of Triangle is A = x ( 2 x - 1 ) cm²  

And The area of triangle with base length 16 cm is 248 cm²

So, option A

Step-by-step explanation:

Given as for a Triangle :

The measure of base of triangle = x cm

Let The height of triangle = ( 2 x - 1 ) cm

Now, Area of Triangle = × hight × base

Or, A =   ×  ( 2 x - 1 ) cm × x cm

Or, A =   x ( 2 x - 1 )   cm²

Again according to question :

Length of base = 16 cm

So , Height of Triangle =  ( 2 x - 1 ) cm =  ( 2×16 - 1 ) cm

I.e  H = 31 cm

∴  Area of Triangle = × hight × base

or, A = × 31 cm × 16 cm

Or, A = 31 cm × 8 cm

I.e A = 248 cm²

Hence The function rule for the area of Triangle is A =   x ( 2 x - 1 ) cm²  

And The area of triangle with base length 16 cm is 248 cm²   Answer

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
