Answer: 91
Step-by-step explanation:
the equation to find the area of a trapezoid is as follows:
A = (a+b)/2h
So A = 6+20 which is 26
then you divide 26 by two which gives you 13, then multiply by 7
Answer:
are you lonly
Step-by-step explanation:
It’s A because the angles are acute and thoses are 25
6x60=360. 4 quarts is equal to 1 gallon so multiply 360 by 4 and you’d get 1440. So the answer should be 1440.
