Answer:
Heather
Step-by-step explanation:
If you use pythagorean theorm you can set up the equations for each girl.
For Heather, 12^2+5^2=13^2 and you determine if this is true. Each side equals 169 so therefore the equation is true.
Answer:
1. ![186\ cm](https://tex.z-dn.net/?f=186%5C%20cm)
2. ![1,960\ cm^2.](https://tex.z-dn.net/?f=1%2C960%5C%20cm%5E2.)
Step-by-step explanation:
Use formulas:
![\text{Perimeter}=2(\text{Width}+\text{Length})\\ \\\text{Area}=\text{Base}\times \text{Height}](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%7D%3D2%28%5Ctext%7BWidth%7D%2B%5Ctext%7BLength%7D%29%5C%5C%20%5C%5C%5Ctext%7BArea%7D%3D%5Ctext%7BBase%7D%5Ctimes%20%5Ctext%7BHeight%7D)
1. From the diagram,
Width = 44 cm
Length = 49 cm,
then
![\text{Perimeter}=2(44+49)=2\times 93=186\ cm](https://tex.z-dn.net/?f=%5Ctext%7BPerimeter%7D%3D2%2844%2B49%29%3D2%5Ctimes%2093%3D186%5C%20cm)
2. From the diagram,
Base = 49 cm
Height = 40 cm,
then
![\text{Area}=49\times 40=1,960\ cm^2.](https://tex.z-dn.net/?f=%5Ctext%7BArea%7D%3D49%5Ctimes%2040%3D1%2C960%5C%20cm%5E2.)
