To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
Answer:
I hope this helps:)
Step-by-step explanation:
Area Y Square + Area of triangle
= 10x10+1/2x18x5
=100+9x5
=100+45
=145.
6+4• (5-7)^2
(5-7)^2
-2^2
4
6+4+4
=14
