Question

#15
area:
(the image shows a triangle with a base of 5.4 in and a height of 2.7 in, asking for the area.)

Explanation:

Step1: Recall the formula for the area of a triangle

The formula for the area of a triangle is $A = \frac{1}{2} \times base \times height$. Here, the base is $5.4$ inches and the height is $2.7$ inches.

Step2: Substitute the values into the formula

Substitute $base = 5.4$ and $height = 2.7$ into the formula: $A=\frac{1}{2}\times5.4\times2.7$.
First, calculate $5.4\times2.7 = 14.58$. Then, multiply by $\frac{1}{2}$: $\frac{1}{2}\times14.58 = 7.29$.

Answer:

The area of the triangle is $7.29$ square inches.
