Question

Which figure has the same area as the parallelogram shown below?

A triangle with a base of 4 mm and a height of 20 mm
A trapezoid with bases of 15 mm and 25 mm and a height of 2 mm
A trapezoid with bases of 6 mm and 14 mm and a height of 8 mm
A rectangle with base 20 mm and height 8 mm

Answer 1

area of parallelogram = base*height
area of triangle = (1/2)*base*height
area of rectangle = length*width
area of trapezoid = (sum of lengths of parallel sides/2)*height
apply as required

Answer 2

so, 8 x 10 (simpler way, it is now a rectangle, so do the formula for it.)

Answer 3

80.

Answer 4

8 x 10 = 80

Answer 5

yep, so what would get that?

Answer 6

A triangle with a base of 4 mm and a height of 20 mm

4 x 20 = 80 x 0.5 = 40
