Question

Cynthia glued a trapezoid with bases of 9 centimeters and 7 centimeters and a height of 6 centimeters onto a rectangular piece of construction paper that measures 20 centimeters by 24 centimeters. How much of the construction paper is not covered by the trapezoid?

Answer 1

Ok so,,,, first you find the area of a trapezoid which is b1 plus b2 times h over 2 so it is 9 plus 7 times 6 divided by two then you get 48 and you subtract by 20 times 24 bc its the area of rectangle so 480 minus 48 which is 432 cm squared
