A piece of cardboard has two circles punched out of it. What is the approximate area of the remaining cardboard? Use 3.14 for pie and round to the nearest whole number.
227 cm2
246 cm2
258 cm2
276 cm2

the complete question in the attached figure

we know that
[the approximate area of the remaining cardboard]=(area of rectangle) - 2(area of circle)

area of rectangle=14 cm* 18 cm------> 252 cm²

area of a circle=pi*r²
r=2/1----> 1 cm
area=pi*1²-----> 3.14 cm²

[the approximate area of the remaining cardboard]=252- 2*3.14
=245.72-------> 246 cm²

the answer is
246 cm²
