Answer:
[tex]\boxed {\tt A= 14 \ ft^2}[/tex]
Step-by-step explanation:
The area of a triangle can be found using the following formula.
[tex]A=\frac{1}{2} bh[/tex]
where [tex]b[/tex] is the base and [tex]h[/tex] is the height.
In this triangle, the base is 7 feet and the height is 4 feet.
[tex]b= 7 \ ft\\h= 4 \ ft[/tex]
Substitute the values into the formula.
[tex]A=\frac{1}{2} bh[/tex]
[tex]A=\frac{1}{2} (7\ ft)(4 ft)[/tex]
Multiply 7 ft and 4 ft.
[tex]A=\frac{1}{2} (28 \ ft^2)[/tex]
Multiply 28 square feet by 1/2 or divide 28 square feet by 2.
[tex]A= 14 \ ft^2[/tex]
The area of the triangle is 14 square feet.
