Question

The perimeter of the rectangle ABCD is
74 units. Find the length of side AB if:

DC (top) = 4z-1
CB (right side) = 3z+3

Answer 1

Answer:

length=19

Step-by-step explanation:

top is length and right side is breadth.

perimeter = 2(l+b)

74 = 2[(4z-1)+(3z+3)]

74/2 = 4z-1+3z+3

37 = 7z+2

7z= 37-2

7z = 35

z = 35/7

z = 5

.: length = top = 4z - 1= 4(5) - 1

= 20-1=19

.: length= 19
