Not enough information. This means that there are many solutions. Therefore, the most complete way to give an answer is in the form of a formula. Set the definition of W and L to: W = width of rectangle L = length of rectangle 2W + 2L = 120 [Perimeter of 120 = (Length*2) + (Width*2)] Which simplifies to {W = 60-L | 0 < L <60} (values for X and Y have to be between 0 and 60, but not exactly 0 or 60) So replace L (length) in the simplified formula with any number that is between 0 and 60. Subtract this number from 60 to determine the corresponding width. For example, I can replace L with 40, and the equation becomes W = 60-40 Simplifies to W = 20 So, one possible solution is W=20 and L=40.

Knowing the area doesn't tell the perimeter. There are an infinite number of different perimeters that can all enclose the same area. The shortest one is a circle. The next shortest is a square. From there, you can actually make the perimeter as large as you want, with no limit, while keeping the area constant. Examples: 30 cm by 40 cm . . . . area = 1,200 cm2 . . . perimeter = 140 cm 10 cm by 120 cm . . . area = 1,200 cm2 . . . perimeter = 260 cm 2 cm by 600 cm . . . . area = 1,200 cm2 . . . perimeter = 1,204 cm 1 cm by 1,200 cm. . . area = 1,200 cm2 . . . perimeter = 2,402 cm 1

The answer is indeterminate, because there are many different rectangles, with different perimeters, whose area can equal 120. Some examples (area being length X width, and perimeter being 2 X length + 2 X width): * Where L=20 & W=6, A=120 and P=40+12=52. * Where L=30 & W=4, A=120 and P=60+8=68. * Where L=60 & W=2, A=120 and P=120+4=124.

The perimeter is 120 cm

Perimeter = 120+60+120+60 = 360 yards

Approximately 4.8 rectangles.

how do you construct a triangle which has a perimeter of 120 and the base angles abc be 30 and 45 degrees

Suppose there are R rectangles and T trapezoids. Then R + T = 540 and T = R + 120 Substituting this value of T in the previous equation gives R + (R + 120) = 540 or 2R + 120 = 540 so that 2R = 420 or R = 210. Then T = R + 120 gives T = 210 + 120 = 330.

120 is possible

It is: 120+80+120+80 = 400 feet

If the asker is referring to area, the answer is 120 feet. Area = base times height (A=bh) A=(12)(10)=120 If the asker is referring to perimeter, then the answer is 44 feet. Since rectangles have 2 sets of congruent sides, perimeter can be defined as 2(Width+length) P=2(10+12)=2(22)=44
