Question

Let's say we have a triangle with sides called a, b, and c, and that b is the base. Our triangle has a height that we'll call h. If a = 11 inches, and b = 3 inches, and c = 11 inches, and h = 10.89 inches, what is the area of this triangle in square inches? Round your answer to the nearest hundredths place. 16.3 16.34 21.9 21.89

Answer 1

Answer:

16.34 square inches.

Step-by-step explanation:

Given:

Base of triangle, b = 3 inches

Height of triangle, h = 10.89 inches

Question asked:

What is the area of this triangle in square inches?

Round your answer to the nearest hundredths place .

Solution:

As we know,

$Area\ of\ triangle =\frac{1}{2} \times base\times height$

                           $=\frac{1}{2} \times3\times10.89\\\\ =\frac{32.67}{2} \\\\ =16.335$

As, we have to find the answer to the nearest hundredths place, hence the area of triangle will be 16.34 square inches.
