The triangular road sign has a base of 30 inches and a height of 40 inches. what is it’s area?

600 in²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = base × height, that is

A = 0.5 × 30 × 40 = 15 × 40 = 600 in²

ANSWER:

The area of the triangular road sign is

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

Where, = area of a triangle

b = base length of the triangle

h = height of the given triangle

hence substituting the values we get

Hence, the area of the triangular road sign with base of 30 inches and a height of 40 inches is

y - y1 = m(x- x1)

y - (-5) = 2/3(x -0)

y + 5 = 2/3x

y = 2/3x - 5
