Exercise 4 Page 829

To find the perimeter, add the three side lengths. To find the area, calculate half of the product of the base and the height.

Perimeter: $54.8 yd$
Area: $80 yd^{2}$

Practice makes perfect

For the given triangle, we will find its perimeter and its area one at a time.

Perimeter

The perimeter of a triangle is calculated by adding its three side lengths.

We are given two side lengths of the triangle,

26

yards and

16

yards, but are missing the third. Note that the side whose length is missing is the hypotenuse of the right triangle formed to the left of the diagram.
