The area of the figure would have to be:
Height × Width
The minimum area would be:
5×5=25 square ft.
To find the minimum height,we devide the area by it's width.
If the painting is 3 3/4 feet wide,the minimum height would have to be:
25÷3 3/4
=25/3×3/4
=25/4 or 6 1/4 ft.
Thus the answer would be:25/4 or 6 1/4 ft.
Hope it helps!
