Determine if the area formula of A=42 bh will always be correct. Find the area by making two right triangles, and by finding the area of the entire triangle by calculating the base. Do you think that the formula A=1/2 bh will work for all types of triangles? Why or why not? Fill in the table below to investigate. Area of Two Right Triangles Area of Entire Triangle Area for Triangle 1: 12 cm Total Base: 15 cm 17,4 cm 112 cm Area for Triangle 2: Area of Entire Triangle: 9 cm 12.6 cm Total Area:​

As part of an annual fundraiser to raise money for diabetes research, diane joined a bikeathon. the track she biked on was 1,920 yards long. diane biked 38.5 laps. her sponsors agreed to donate an amount of money for each mile she biked. how many miles did she bike? first fill in the blanks on the left side using the ratios shown. then write your answer. given ratios: 5280ft / 1 mi , 1 mi /5280 ft , 1,920 yards / 1 lap , 1 lap / 1,920 yards , 3 ft / 1 yard , 1 yard / 3 ft. blanks: 38.5 laps / 1 yard x (blank) x (blank) x (blank) = (blank) miles i'm really confused on how to do this, and the explanations aren't exactly . if you could walk me through how to do this, it would be greatly appreciated.
