Arectangular field is 4 times as long as it is wide. if the length is decreased by 10 feet and the width is increased by 2 feet, the perimeter will be 80 feet. find the dimensions of the original field. the original dimensions are feet long by feet wide.

Iknow its nothing to do with education, but what type of thing should i wrote here? ? : ) its for mcdonald's btw.

Consider the following geometry problems in 3-space enter t or f depending on whether the statement is true or false.
