Question

1. determine the perimeter of the shaded figure. perimeter = yds 25 yds 30 yds 10 yd 10 yds

Explanation:

Step1: Identify side - lengths

The vertical sides of the shaded figure: two sides of length $30$ yds. The horizontal sides: two sides of length $25$ yds and two sides of length $10$ yds.

Step2: Calculate perimeter

The perimeter formula for a polygon is the sum of all side - lengths. $P=2\times30 + 2\times25+2\times10$.
$P = 60+50 + 20$.
$P=130$ yds.

Answer:

$130$
