Question

Find the area of each figure. Round to the nearest tenth if necessary.

A triangle with a base of 12 millimeters and height of 11 millimeters

Short answer

The area of the triangle is $66{\mathrm{mm}}^2$.

Step-by-step solution

Step 1. Given information.

A triangle with base of 12 millimeters and height of a 11 millimeters.

Step 2. Concept used.

The area of the triangle is half into a product of its height and base. Let the base beb and the height be h then it is mathematically denoted by $A=\frac{1}{2}·b·h$.

Step 3. Calculations.

$$\begin{gathered} A=\frac{1}{2}·b·h \\ =\frac{1}{2}·12·11 \\ =66{\mathrm{mm}}^2 \end{gathered}$$

Thus, the area of the triangle is $66{\mathrm{mm}}^2$.
