Answer:

A = 19 [tex]\frac{1}{2} [/tex] ft²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2} [/tex] bh ( b is the base and h the height ) , then

A = [tex]\frac{1}{2} [/tex] × 4 [tex]\frac{7}{8} [/tex] × 8 ( change mixed number to improper fraction )

  = [tex]\frac{1}{2} [/tex] × [tex]\frac{39}{8} [/tex] × 8 ( cancel 8 on numerator/ denominator )

  = [tex]\frac{1}{2} [/tex] × 39

  = [tex]\frac{39}{2} [/tex]

  = 19 [tex]\frac{1}{2} [/tex] ft²
