Calculate the area of a rectangle whose sides are equal; (√7 + 4) cm and (4-√7) cm
| September 8, 2021 | education
The formula for finding the area of a rectangle is as follows:
S = a * b, where a and b are two non-opposite sides of the rectangle.
We have the size of the sides of the rectangle, so we will find its area.
S = (v7 + 4) * (4 – v7) = 4v7 – 7 + 16 – 4v7 = -7 + 16 = 9 cm2, where v is the square root.
Answer: The area of a rectangle with sides (√7 + 4) cm and (4 – √7) cm is equal to 9 square centimeters.
