1. Saurabh has purchased a square sheet of plywood 196 square feet area. To cover a wall he must cut off 3 feet from a side. What is the area in square feet of the wall?
- A. 154
- B. 154
- C. 154
- D. 154
Answer: Option A
Explanation:
Side of the plywood = √169 = 13 feet
Cutting of 2 feet from a side will make it a rectangular sheet with a length of 13 feet and a width of 11 feet. Area of the wall is equal to the area of this sheet.
So, the area of the wall = 13 x 11 = 143 sq ft
