of 40 feet?
A=200 square ft
A=800 square ft
A=400 square ft
A-600 square ft

Respuesta :

Answer:

A = 400 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 vertical height ) , then

A = [tex]\frac{1}{2}[/tex] × 20 × 40 = 10 × 40 = 400 ft²
