The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length
rosijanka [135]

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

Perimeter = 50

a=b + 1

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

Perimeter = 2(a + b)

Make b the subject in a=b + 1

b = a -1

Substitute a - 1 for b and 50 for Perimeter in Perimeter = 2(a + b)

50 = 2(a + a - 1)

Divide through by 2

25 = a + a - 1

25 = 2a- 1

Add 1 to both sides

25 + 1 = 2a - 1 +1

25 + 1 = 2a

26 = 2a

Solve for a

a = 26/2

a = 13

<em>Hence, the length of the longest side is 13mm</em>
