35 square units is the area.
Length + width = ½ of perimeter ie 9 units. Area could be anything from 8 square units (8 x 1) to 20 square units (5 x 4), assuming there are no fractional measurements and that rectangle is not a square.
If you are talking about a rectangle, you can't find the area from just the perimeter. With a perimeter of say 80 units, the sides could be 10 and 30, with an area of 300 square units. But the sides could also be 5 and 35, with an area of 175 square units. There are lots of other possibilities. If you are talking about a square, that's different. Each side is a quarter of the perimeter, so the area is a quarter of the perimeter multiplied by a quarter of the perimeter.
A 5 x 7 rectangle
This question does not contain enough information. Is it a sqare? a rectangle? a triangle? a polyhedron? if it was a square it would be 1225/16 units squared.
Perimeter = 24 inches Area = 35 square inches
About 3,848.45 square units.
Any positive value upto 36 square units. A 6x6 square will have the maximum area of 36 sq units; a 5x7 rectangle will have an area of 35 sq units, and the area will be reduced as you reduce one of the measures and increase the other so that their sum remains 12 units so that the perimeter is 24 units. 1x11 will be 11 sq units 0.1x11.9 will be 1.19 sq units 0.01x11.99 will be 0.1199 sq units 0.001x11.999 will be 0.011999 sq units, etc.
The area of rectangle is : 35.0
If the figure is a rectangle then it is:- 18*35 = 630 square units
The perimeter of a 35-acre square lot is 0.935 miles.
