Question

What is the area of a triangle with a base of 4 7/8 ft and a height of 8 ft? (ignore the clicked answer it was an accident lol)

Answer 1

A = 19
`(1)/(2)` ft²

Explanation:

The area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the height ) , then

A =
`(1)/(2)` × 4
`(7)/(8)` × 8 ( change mixed number to improper fraction )

=
`(1)/(2)` ×
`(39)/(8)` × 8 ( cancel 8 on numerator/ denominator )

=
`(1)/(2)` × 39

=
`(39)/(2)`

= 19
`(1)/(2)` ft²
