Find the area of a rectangle with sides equal to A) 6 cm and 7 cm B) 10mm and 8mm C) 25m and 30m

a) The area of the rectangle is found by the formula:

S = a * b, where a is the length, b is the width.

S = 6 * 7 = 42 cm2.

Answer: the area of the rectangle is 42 cm2.

b) Let’s find what the area of the rectangle is, if its length and width are known:

S = a * b, where a is the length, b is the width.

S = 10 * 8 = 80 mm2.

Answer: S = 80 mm2.

c) Determine what the area of the rectangle is if, according to the condition of the problem, it is known that the width is 25 m and the length is 30 m:

S = a * b, where a is the length, b is the width.

S = 25 * 30 = 750 m2.

Answer: the area of the rectangle = 80 mm2.
