Answer:
1024 cm²
Step-by-step explanation:
There are 16 rods. A square has 4 equal sides, so each side must consist of 4 rods. The length of each rod is 8 cm, so the length of each of the square's sides is 32 cm. Therefore, the area of the square is:
A = s²
A = (32 cm)²
A = 1024 cm²
Simplify the equation
Since
and
we have
2.159 • 10⁴⁵
you move the decimal point until you get a one digit decimal.
87
66 + 72 + 87 = 225
225 / 3 = 75
