1.) An angle that measures greater than 90° but less than a straight angle (the angle measure of a straight line, which is 180°) is called an Obtuse Angle.

2.) The perimeter is the total distance used to enclose a 2-D space. In other words, it’s the total distance around the shape, or used to form the shape.

Mathematically, this is calculated as the sum of all side lengths. So, we’ll add all the side lengths together to get the perimeter. We’ll use “p” to symbolize perimeter Algebraically, so p=perimeter.

p=40+35+25+70+(70-40)

Notice that we must find the side length of one of the sides, and we can do so by realizing that 40+x=70, where x=side length. This is simply the same as x=70-40.

p=200

So, the perimeter is 200ft²
