Answer:

Step-by-step explanation:
<u>Finding the smaller side</u> :
⇒ P = 2(l + w)
⇒ 20 = 2(6 + w)
⇒ 6 + w = 10
⇒ w = 4 cm
<u>Finding area</u> :
⇒ 6 × 4
⇒ 24 cm²
30-24=6 6/30=0.2
0.2x100=20
20%
B? I think ( do not come at me if it’s wrong)
Move all the terms to the left side and set equal to zero. Then set each factor equal to zero.
A= c+d/b+d
Answer:
s=-4
Step-by-step explanation:

- subtract 3s from both sides to get -12=3s
- divide both sides by three and get s=-4
