The length of the rectangle is 6 cm. What is its area if the perimeter is 18 cm?

Given:
dl = 6 cm
Rpr = 18 cm
Spr =?
solution :
the formula for finding the area of a rectangle is: Spr = a * b, where a is the length of the rectangle, b is the width of the rectangle. to find the area, we need to know the width. The width can be expressed from the formula for the perimeter of the rectangle: Ppr = 2 * (a + b) … b = (Rpr: 2) -a
calculate the width by substituting the values into the formula: b = (18: 2) – 6 = 3 (cm)
now, knowing the width, we find the area of the rectangle: Spr = 6 * 3 = 18 (cm2)
ANSWER: RECTANGLE AREA = 18 CM2.
