An A-frame cabin has a triangular front with a base of 30 ft and a

height of 20 ft. If the front is to be glass that costs $3 per square foot, what will the glass cost?

$1,800?

The area of the triangle is A = 1/2 of the base times the height.

A= bh/2
A = ?

$900?

Right.

To calculate the cost of the glass for the A-frame cabin, we need to find the area of the triangular front and then multiply it by the cost per square foot.

The formula to calculate the area of a triangle is:

Area = (base * height) / 2

Substituting the given values:

Area = (30 ft * 20 ft) / 2
= 600 ft²

Now, we can calculate the cost of the glass by multiplying the area by the cost per square foot:

Cost = Area * Cost per square foot
= 600 ft² * $3/ft²
= $1800

Therefore, the cost of the glass for the A-frame cabin is $1800.
