Find the area of the regular brainliest given, bogus answers reported

The area is

A = 2·7^2 = 98 yd²

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

don't give

take it once

try and try and you will not

happy to

pls mark as brainliest
