Answer 1

Answer: The answer is (16 × 4 and 15 × 3) and (8 × 8 and 7 × 7).

Step-by-step explanation: Given that the area of the frame was 64 sq. inches. We need to find the two possible sets of dimensions that we can use to make the frame with such area.

Since the outer lining of the frame is 1 inch larger than the inner lining, so the length and breadth of the outer lining will be length and breadth of the inner lining plus one.

Given area of the frame is 64 sq. inches, so the possible sets of dimensions that we can use are given by

(a) Outer 16 × 4 and inner 15 × 3,

(b) Outer 8 × 8 and inner 7 × 7.
