Answer: The photo will be 36 inches tall.
Given:
Original width or breadth (L1) of the rectangular photo = 6 inches
Original height or length (L1) of the rectangular photo = 12 inches
Original area (A1) = B1 x L1
= 6 x 12 = 72 square inches
New width (B2) = 2 inches
According to the question, original area (A1) should be equal to new area (A2).
Therefore, let us formulate:
A1 = A2
B1 x L1 = B2 x L2
The value of L2 is unknown.
So, 72 = 2 x L2
By the method of transposition,
L2 = 72 รท 2 = 36 inches
