Question

The area of a square field is 841 m2 .a rectangular field whose length is twice it's breadth has its perimeter equal to the Smallest of the square field.find the area of the rectangular field

Answer 1

Answer:

747.56

Step-by-step explanation:

by the question, l=2b (equation 1)

length of sides of the square=√841 = 29

perimeter of square : 4*29 = 116

perimeter of the rectangle: 2l + 2b= 116

from equation 1: l=2b

so perimeter is 4b+2b=116

6b=116

b=19.3

l=2b= 2*19.3= 38.67

area= l*b= 38.67*19.3 = 747.56
