Answer: Equation that represents this problem is
2b+5=74

The base of the triangle is 34.5 mm.

Explanation:

Let b represents the base length of the triangle in mm.

Given : The height of a triangle is 5 more than double the base length.

i.e. Height = 2b+5

If the height of the triangle is 74 mm, then the equation that represents this problem is
2b+5=74

To find b , first subtract 5 from both sides of the equation, we get


2b=69\\\\\Rightarrow\ b=34.5 [Divide both sides by 2]

Hence, the base of the triangle is 34.5 mm.
