Answer 4

4.
The area of a regular octagon is 35 cm². What is the area of a regular octagon with sides three times as long? (1 point)

Answer 5

315 cm²
175 cm²
225 cm²
105 cm²

Answer 6

I did this question yesterday.

8. The area of an octagon is a²(2+2√2) where a is side length

So we know

35 = a²(2+2√2)
A = (8a)²(2+2√2)

Rearrange the first in terms of a²
a² = 35 / (2+2√2)

Substitute in the second and the (2+2√2) terms cancel out

A = 64 * 35 = 2,240cm²

Answer 7

The area increases with the square of the side length, so a 3x increase in side length corresponds to a 9x increase in area. The new area is 35x9=315cm2.
