August 22, 2021
The area of a rectangle is equal to the product of its length and width.
Let’s write down the formula for the area of a rectangle. Let us denote the area by the letter S, the length by the letter a, and the width by the letter b:
S = a × b.
Substitute the known values of the length and width of the rectangle into the formula:
S = a × b
S = √45 × √5
S = √225
S = 15 〖cm〗 ^ 2
Answer: the area of the rectangle is 15 〖cm〗 ^ 2
