The length of the rectangle is 6 cm, and its area is 24 cm2 A) find the width of this rectangle. b) build this rectangle (but you do not build) c) find the perimeter of this rectangle.
1) Find out what width the rectangle has, if it is known that its length is 6 cm, and the area is 24 cm2.
The area of the rectangle is calculated by the formula:
S = a * b. It follows that:
a = S / b.
24/6 = 4 cm.
2) Find the perimeter of the rectangle if it is known that its length is 6 cm and its width is 4 cm.
The perimeter of a rectangle is calculated by the formula:
P = a * 2 + b * 2.
4 * 2 + 6 * 2 = 8 + 12 = 20 cm.
Answer: the width of the rectangle is 4 cm, and its perimeter is 20 cm.
