Please help me out. Good points given.

expression for perimeter 3x+12

expresion for area ( 2x+6) ( x+4) /2

P= 29; A = 72

Step-by-step explanation:

Given : hight 2x+6, base length x+4 and triangle is equilateral

perimeter = base + two other sides

because the triangle is equilateral the base length is the same as the other two sides

perimeter = x+4 + x+4 +x+4 = 3x + 12

area = base *hight / 2 = (x+4) ( 2x+6) /2  

if x=5

P = 3*5 +12 = 29, A = (5+4) ( 2*5+6)/2 = 9* 16/2 = 144/2 = 72

answer: idk

step-by-step explanation:

answer: input the dimensions of the room to be painted. click the button to calculate the amount of paint and man-hours needed for this job.

interior paint coverage depends on the brand of paint used. the coverage amount is listed on the label of the paint can. use this to adjust the values in the paint coverage section below. paint usually is applied at 350 to 400 square feet per gallon (primer at 200 to 300 square feet per gallon).
