Answer:
128 square inches
Explanation:
The formula for the area of a rectangle is
Length × Width
There are 2 rectangular windows in ms. Ridleys dining room.
For Window A
One window is 31 inches wide and 32 inches tall.
Length × Width
= 32 inches × 31 inches
= 992 square inches
For Window B
The other window is 27 inches wide and 32 inches tall.
Length × Width
= 32 inches × 27 inches
= 864 square inches
Hence, the difference in the area of the windows in ms. Ridleys dining room is calculated as:
Area of Window A - Area of Window B
= 992 square inches - 864 square inches
= 128 square inches
