4. Find the Area of the trapezoid.

40 in^2

Step-by-step explanation:

The area of the trapezoid is found by

A = 1/2 (b1+b2)h  where b1 and b2 are the lengths of the bases and h is the height

   = 1/2 (7+3)*8

   = 1/2 (10)*8

   = 40 in^2

ok the answer is 40

Step-by-step explanation:

a+b/2*h

7+3/2*8

7+3=10

10/2=5

5*8=40

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
