7*7 = 49 square units
Thanks to limitations of the browser used for posting questions, it is not possible to tell whether the sides are 6x - 7 units or 6x + 7 units. For 6x - 7 units, area = 36x2 - 84x + 49 square units. For 6x + 7 units, area = 36x2 + 84x + 49 square units.
A triangle with side a: 7, side b: 12, and side c: 11 units has an area of 37.95 square units.
7 * 2 = 14Fourteen square units
A rectangular area 9 units by 7 units has an area of 63 square units.
(2x-7)(2x-7) = area 4x2-28x+49 = area
It has a perimeter of 12 units, an area of 7 (6.9282) square units and an altitude of 3.5 (3.4641) units.
42 square units
If a square has an area of 12 square units, then as all its sides are the same length (by definition), each side will be √12 units longs, ie approx 3.46 units long.If you mean a Rectangle has an area of 12 square units and one side is 2.1 units long, then the other side is:area_rectangle = length × width→ width = area_rectangle ÷ length→ width = 12 units² ÷ 2.1 units→ width = 5 5/7 units ≈ 5.7 units.The "height" is approx 5.7 units long.
105/7 = 15 units
(7*x)/2 = area in square units
A 7-by-9 grid has an area of 63 square units.
