2) 1.2 x 10,000 - 1.5 x 1,000 - 2.2 x 100 = 10,280 3) 7.3 x 100,000 + 1.6 x 1,000,000 + 4.7 x 100,000 = 2,800,000 4) 8.2 x 10,000 - 2.4 x 10,000 - 1.5 x 1,000 = 56,500 5) 2.4 x 1,000 + 3.4 x 10,000 + 1.5 x 1,000 = 37,900 6) 6.2 x 10,000 - 3.4 x 100 - 7.5 x 1,000 = 54,160 7) 8.3 x 100,000 + 1.6 x 10,000,000 + 6.7 x 10,000 = 16,897,000 8) 8.0 x 1,000 - 0.8 x 1,000 - 1.2 x 100 = 7,080
So the equation for a trapezoid is , with the b variable being the 2 bases, h variable for height, and the a variable for area. Firstly, we will need to plug in the appropriate numbers into the equation, and it'll look like this:
Next, we will need to combine 12 and 14, then divide the sum by 2. Your equation should look like this:
Lastly, just divide each side by 13, and your answer should be
