Answer: length = 40cm
Step-by-step explanation: 2(l+b):b=26:5
10l+10b = 26b
10l = 16b
b = 5/8l
Area = l*b=1000
l*5/8l = 1000
l2 = 1600
l=40cm.

Step-by-step explanation:
The ratio between the perimeter and the breadth of a rectangle is 26:5 . If the area of the rectangle is 1000 sq. cm, what is the length of the rectangle?
Solution: (2L+2B):B = 26.5:5, or
26.5B = 10L+10B, or
16.5B = 10L, or
L = 1.65B
LB = 1000, or
B*1.65B = 1000, or
B² = 1000/1.65 = 606.060606,
B = 24.6182982 cm and
L = 40.62019202 cm.
The length of the rectangle = 40.62 cm.
