Answer:
459
Step-by-step explanation:
first we solve the area of the rectangle. the length of the rectangle is 22 and the width is 18. 22 times 18=396. next we need to solve the area of the triangle. 7 is the height of the triangle and 18 is the width. 7 times 18 divided by 2 is 63. Next we need to add up the area of the rectangle and the triangle
396+63=459
Answer: 'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
8% = 8/100 = 8 ÷ 100 = 0.08.
100% = 100/100 = 100 ÷ 100 = 1.
Step-by-step explanation:
To calculate percentage decrease:
First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100. If your answer is a negative number, then this is a percentage increase.
