Answer:

options B and C

Explanation:

The area of the parallelogram is given by:

Area = base x height

Area = 10mm x 8mm

Area = 80mm^2

To determine which figure has the same area as the parallelogram, we can calculate the area of each option and compare it to 80mm^2.

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

Area = (1/2) x base x height = (1/2) x 4mm x 20mm = 40mm^2

This option does not have the same area as the parallelogram.

B. A trapezoid with bases of 15mm and 25mm and a height of 2mm.

Area = (1/2) x (base1 + base2) x height = (1/2) x (15mm + 25mm) x 2mm = 80mm^2

This option has the same area as the parallelogram.

C. A trapezoid with bases of 6mm and 14mm and a height of 8mm

Area = (1/2) x (base1 + base2) x height = (1/2) x (6mm + 14mm) x 8mm = 80mm^2

This option has the same area as the parallelogram.

D. A rectangle with a base of 20mm and height of 8mm.

Area = base x height = 20mm x 8mm = 160mm^2

This option does not have the same area as the parallelogram.

Therefore, the figures that have the same area as the given parallelogram are options B and C, both with an area of 40mm^2.

Answer:

C. A trapezoid with bases of 6mm and 14mm and a height of 8mm

Explanation:

First thing you want to do is find out the Area of a Parallelogram.

A = BH

so that would be
80 mm

then we go down the list

A. Wouldn’t work 1/2bh

Which is 20mm

B.WOULDNT WORK which is 40mm with area of a trapezoid formula

C. WOULD WORK A= 80 mm

A=a+b2h=6+142·8=80

D. Wouldn’t work
