Question

Q3. Three - fourth part of a rectangular field is divided into 39 small rectangular fields of sides 9 m and 4 m respectively and perimeter of rectangular field is 176 m . What is the length of the longer side of the rectangular field ?​

Answer 1

Step-by-step explanation:

let the breadth be x

length is 4+2×

perimeter equals to 176 m

( x + 4 + 2 × ) 2 = 176 m

x + 4 + 2 × equals to 176/2

3 × + = 88

3 × 84

therefore X equals to 28

breadth is 28

length is 2 × + 4 that is 60
