Answer:
600 in²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] base × height, that is
A = 0.5 × 30 × 40 = 15 × 40 = 600 in²
ANSWER:
The area of the triangular road sign is [tex]600 \mathrm{ln}^{2}[/tex]
SOLUTION:
We need to find the area of the road sign, which is in triangular shape.
So, we need to calculate the area of a triangle.
Given, length of the base of the given triangle = 30 inches
Height of the given triangle = 40 inches
We know that,
area of the triangle [tex]\Delta=\frac{1}{2} \times b \times h[/tex]
Where, [tex]\Delta[/tex] = area of a triangle
b = base length of the triangle
h = height of the given triangle
hence substituting the values we get
[tex]\Delta=\frac{1}{2} \times 30 \times 40[/tex]
[tex]=\frac{1}{2} \times 1200[/tex]
[tex]=600 \ln ^{2}[/tex]
Hence, the area of the triangular road sign with base of 30 inches and a height of 40 inches is [tex]600 \ln ^{2}[/tex]
