Answer:
A= 71 3/4 ft
Explanation:
The formula for a parallelogram is A=bh (b= base) (h=height)
So, this parallelogram has a base of 10 1/4 and a height of 7.
Now that we have the values we need all you do is multiple them together.
10 1/4 * 7 = 71 3/4 ft
If you have a problem with multiplying fractions another way to rewrite 10 1/4 is 10.25 since 1/4 of a quarter is .25.
So you can also do 10.25 * 7 and you would get 71.75 which is the same answer just in decimal form.
If you rewrite 71.75 as a fraction it would be 71 3/4 since .75 is 3/4 of a quarter.
Hope this helps!
