Step-by-step explanation:
Answer:
22 ft by 18 ft
Step-by-step explanation:
Area = l * w
Area = (x+8) * (x+4) = x^2 +12x+32
396 = x^2 +12x+32
400 = (x+6)^2
20 = x+6
x = 14
x+8 = 22
x+4 = 18
<span>We can say that 20 students represent 100 % and that 4 students represent x % of all students. Then we can use the proportion: 20 : 4 = 100 : x, or 20 / 4 = 100 / x. Then we will cross multiply: 20 x = 4 * 100, 20 x = 400, x = 400 : 20 , x = 20 %. Also we can say that 4 = 1/5 * 20 and 1/5 * 100 = 20 % Answer: 4 students is 20 % of 20 students. Hope this helps.
