Answer:
14cm
Step-by-step explanation:
Triangle area formula:
(B*H)/2=A
B = base/bottom
H = height or length
A = total area
(7*4)/2 = 14
DONT FORGET TO ADD THE UNIT! (in this case it's cm)
The area of a triangle with a base of 7 centimeters and height of 4 centimeters is 14 square centimeters.
To find the area of a triangle, we use the measurements of its base and height.
The formula used to find the area of a triangle given its base (b) and height (h) is:
[tex]\displaystyle A=\frac{1}{2}bh[/tex]
To find the area of the given triangle, we use the formula above combined with the values we know.
Substitute in the known values, given b=7cm and h=4cm:
[tex]\displaystyle A=\frac{1}{2}\cdot7\textsf{ cm}\cdot4\textsf{ cm}[/tex]
Simplify with multiplication:
[tex]A=\boxed{14\textsf{ cm}^2}[/tex]
Note: since we multiplied centimeters by centimeters, the result will be in square units, or [tex]\textsf{cm}^2[/tex].
