Question

In exchange for a square plot of land one of whose side is 84m,a man wants to buy a rectangle plot 144nlong and of the same area as the square plot. Determine the width of rectangle plot

Answer 1

Answer:

49m

Step-by-step explanation:

Area of square = side^2 = 7056

Area of rectangle = length × breadth = 144 × b

 

144 × b = 7056

b = 49

The width of rectangular plot is 49 m

Answer 2

Side of square plot = 84m

Length of rectangle = 144m

Area of Rectangle = Area of Square

Length ×Breadth = side ×side

144 ×B = 84 ×84

$b = \frac{84 \times 84}{144} \\ b=7 \times 7 = 49$
