Answer:
3 6/10 square feet
Step-by-step explanation:
The area of the rectangle is 8 1/10
The width of the rectangle is 2 1/4
We are required to find the length
Area= length × width
Length= Area/width
= 81/10 / 9/4
= 81/10 × 4/9
= 36/10
= 3 6/10
Hence the length of the rectangle is 3 6/10 square feet
