What is the length of this garden A rectangular garden has a perimeter of 48 cm and an area of 140 sq cm?
The area is A and the parameter is P.Two sides of the garden must be length a and the other two sides must be length b.ab = A = 1402a + 2b = P = 48ab = 140 and2a = 48 - 2bdividing bother sides by 2:a = 24 - bPlugging in this formula for a in terms of b into the equation for area we can conclude that:(24 - b)b = 14024b - b2 = 1400 = b2 - 24b + 140This can be factored as such:0 = (b - 14)(b - 10)therefore b = 10, 14.Logically, b can only be either 10 or 14, and amust be the other value.

The difference between two supplementary angles is 20 degrees what are the angles?
If A and B are the angles, then A + B = 180 and A - B = 20 So that 2A = 200 ie A = 100 and then B = 80 So the two angles are 100 and 80 degrees.
If A exceeds B by 40 percent and B is less than C by 20 percent then A is to C is?
Assume that B is 100% A therefore is 140% —> B + 40% C therefore is 120% —> B + 20% Therefore A : C = 140 : 120 Therefore A exceeds C by 16.67%
