Answer:
A trapezoid with bottom side length of 2 centimeters, height of 2 centimeters, and top side length of 1.5 centimeters
Explanation:
The area of a trapezoid is given by ...
A = (1/2)(b1 +b2)h
where b1 and b2 are the lengths of the parallel bases (top side, bottom side) and h is the height. (A triangle is a trapezoid with a topside base of 0.)
The areas of your figures are ...
- (1/2)(3 +1.5)(2) = 4.5
- (1/2)(3 +1.5)(2) = 4.5
- (1/2)(3 +0)(2) = 3
- (1/2)(2 +1.5)(2) = 3.5 . . . . this trapezoid has an area of 3.5 cm^2
The last figure has the required area.
