If the height of the triangle is 3 units more than the base, select the function that represents the area of the triangle.
vesna_86 [32]

For this case we have that by definition, the area of a triangle is given by:

A = \frac {1} {2} * b * h

Where:

h: It's the height of the triangle

b: It is the base of the triangle.

They tell us that the height of the triangle is 3 units more than the base. That means that if the base is "b" then the height is "b + 3". So, the area is:

A(b) = \frac {1} {2} * b * (b + 3)\\A(b) = \frac {1} {2} * b ^ 2 + 3b\\A(b) = \frac {b ^ 2 + 3b} {2}

An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How ta
hichkok12 [17]

Answer: 1.2 m

Step-by-step explanation:

Given

The length of the ramp to the building is 3.7 m

Distance from the beginning of the ramp to the base of the building is 3.5 m.

Suppose h is the height of the ramp

from the figure, we can write

\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m

So, the height of the ramp is 1.2 m
