If a parallelogram and a triangle have the same area, this means 1 of the dimensions of the parallelogram will be half the dimension of the triangle.

Ex : triangle b= 10, h= 4
A = 40/2 or 20 square units

Parallelogram b = 5, h= 4
A = 5 x 4 or 20 square units

We are going to form a triangle of base 10 inches ans height 5 finches; also, the eight of our triangle will be the width of our rectangle (a rectangle is a parallelogram). First, we are going to use the area of a triangle formula:
A= (1)/(2) bh
where

A is the area in square inches

b is the base of the triangle

h is the height of the triangle
We know that
b=10 and
h=5, so lets replace those values in our formula:

A= (1)/(2) (10)(50)

A= (1)/(2)(50)

A=25

Now that we have the area of our triangle, we are going to use the area of a rectangle formula:
A=wl
where

A is the area in square inches

w is the width of the rectangle

l is the length of the rectangle
Since the width of our rectangle is equal to the height of our triangle,
w=5. Also, we know for our problem that the area of our triangle and the area of our triangle must be equal, so
A=25. Lets replace those values in our formula to find the length of our rectangle:

A=wl

25=5l

l= (25)/(5)

l=5

We can conclude that the dimensions of our triangle are: base=10 inches and height= 5 inches, and the dimensions of our parallelogram are: width= 5 inches and length= 5 inches.
