For this case, we have that by definition, the area of a triangle is given by:

A = \frac {b * h} {2}

where:

b: It's the base

h: It's the height

In this case we have:

b = 21 \ ft\\h = 6 \ ft

Substituting:

A = \frac {21 * 6} {2}\\A = 63 \ ft ^ 2

Answer:

63 \ ft ^ 2

Arturiano [62]

Answer: 25 bikes and 55 cars were used.

Step-by-step explanation:

Let b represent number of bicycles that the students ride to school.

Let c represent number of cars that the students drive to school.

At Billy's school, 80 students come to school by bike or car. It means that

b + c = 80

A bike has 2 wheels. A car has 4 wheels. Together the vehicles that arrive at the school have 270 wheels. It means that

2b + 4c = 270- - - - - - - - - - 1

Substituting b = 80 - c into equation 1, it becomes

2(80 - c) + 4c = 270

160 - 2c + 4c = 270

- 2c + 4c = 270 - 160

2c = 110

c = 110/2

c = 55

b = 80 - c = 80 - 55

b = 25
