Question

find the area of \\( \triangle gem \\).
round your answer to the nearest tenth.
use the keypad to enter the answer in the box provided.
the area of \\( \triangle gem \\) is \\( \square \\) square units.

Explanation:

Step1: Determine the base and height

Assume the distance between \(G\) and \(M\) as the base \(b\). Counting the units on the grid, \(b = 9\) units. The height \(h\) (perpendicular from the base) is \(3\) units.

Step2: Use the triangle - area formula

The formula for the area of a triangle is \(A=\frac{1}{2}bh\). Substitute \(b = 9\) and \(h = 3\) into the formula: \(A=\frac{1}{2}\times9\times3=\frac{27}{2}=13.5\)

Answer:

\(13.5\)
