Answer:
The possible dimensions are (21 ,2) , (3,14) , (1,42) , (6,7)
Step-by-step explanation:
Let the dimensions of the rectangle be X and Y.
![X\times Y = 42](https://tex.z-dn.net/?f=X%5Ctimes%20Y%20%3D%2042)
Therefore if we find the factors of 42 we will get the dimensions of the triangle.
factors of rectangle are (21,2) , (3,14) , (1,42) , (6,7).
therefore possible dimensions are (21,2) , (3,14) , (1,42) , (6,7).
