Answer:
perimeter is adding so add all the sides
Step-by-step explanation:
The answer to both equations is 'A'. For the first you just input the value of 20 to replace n and get 700. (Side-note: the number 20, which is your variable, should be nowhere in the function so you know b is wrong). so now that you have your answer 700 the second part is self explanatory.

Answer:
24units squared
Step-by-step explanation:
The area of a triangle is B*H/2=A so 8*6=48. 48/2=24
9514 1404 393
Answer:
32 dm
Step-by-step explanation:
Use the formula for the area of a triangle, and solve for the unknown.
A = 1/2bh
200 dm² = 1/2(12.5 dm)b
b = (200 dm²)/(6.25 dm) = 32 dm
The base of the triangle is 32 dm.
