How to find HF
using the values above how do I find HF. I don’t understand how.

The value of HF is 16.

Solution:

Given data:

GF = 20 and EF = 25

To find HF:

Using geometric mean of right triangles,

GF² = HF × EF

(20)^2 = HF × 25

400 = HF × 25

Divide by 25 on both sides.

16 = HF

The value of HF is 16.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
