1/5(80)

Step-by-step explanation:

Well, 45% of 76 is 34.2

Which can be solved by converting 45% to .45 and then multiplied by 76

1/4(80) can be converted into .25*80 which is 20

1/5(80) can be converted into .20*80 which is 16

1/2(80) can be converted into .50*80 which is 40

1/9(80) can be converted into .11*80 which is 8.88

The closest one is 1/5(80) which solves the estimate,

so the rectangle is 80cm (area)

now to find the area of a triangle.
