The height of the triangle is 7 cm longer than its base. the area of the triangle is 60 cm squared. what is the base of the triangle?

8 cm

Step-by-step explanation:

Let x cm be the length of the base, then the length of the height is x+7 cm. Use formula for the area of the triangle:

In your case,

Since the base cannot have negative length, then x=8 cm.

Base = 8 cm

Step-by-step explanation:

We are given that the height of a triangle is 7 cm longer than its base and its area is 60 cm squared.

We are to find the base of the triangle.

Area of the triangle =

Assuming the base to be , so height will be

Substituting the values in the above formula to get:

Factorizing the quadratic equation to get:

and

Since base cannot be negative so it will be 8 cm.
