Question

A triangular college pennant flag has a baes of 12 inches and a height of 30 inches how many square inches of wall space will you need to hang up six pennants?

Answer 1

`1080 \ in^2`

Explanation:

-The cumulative area of the six is equivalent to the sum of their individual areas.

-Area of a triangle is given by:

`A=(1)/(2)bh\\\\b-base \ length\\h-\perp Height`

We substitute given values in the equation and multiply by the number of pennants:

`A=(1)/(2)bh* 6\\\\=(1)/(2)* 12* 30* 6\\\\=1080\ in^2`

Hence, the total area needed is
`1080 \ in^2`
