------> equation A
where
b is the base of the triangle
h is the height of the triangle
In this problem the dimensions of the triangle are increased by a scale factor of
so
the new dimensions of the triangle are
The new area of the triangle will be
------> equation B
Substitute equation A in equation B

Answer: The equation to find Number of grand seats, s are either of the following
x+ s= Total seats
x+s= 19,000
5000+s= 19,000
Number of grand seats, s= 14,000
Step-by-step explanation:
Step 1
A stadium had a total of 19,000 seats.
Given that field seats=5,500
And the rest which are grandstand seats=?
Let field seats be represented as x and grand seats be represented as s
such that the total number of seats can be expressed as
x+ s = Total seats
x+ s= 19,000-------- Equation.
5000+s= 19,000
Step 2
Such that given field seats, x= 5000, Number of grand seats will now be
x + s= 19,000
5000 + s= 19,000
s= 19,000-5000
=14,000 seats
