Question

find the width of a 144 M long rectangular plot whose area is same as that of a square plot having is side as 84 m

Answer 1

Answer:

49 m

Step-by-step explanation:

Area of a rectangle = length × breadth .

Area of a square = side × side .

Now side of square = 84 m .

Area of the square plot = 84 m × 84 m

Area of the rectangle is given same as that of the square .

This means that length × breadth = 84 m × 84 m

Given length = 144 m

Breadth = ?

So breadth × 144 m = 84 m × 84 m

= > breadth = ( 84 m × 84 m ) / 144 m

= > breadth = 7 m × 7 m

= > breadth = 49 m

Breadth is the width of a rectangle.

The answer to your question is 49 m .

Answer 2

Length of rectangle =144m
Rectangular Area= Square plot Area
Length×Breadth = side×side
$144 \times b = 84 \times 84 \\ b = \frac{84 \times 84}{144} \\ b = 49$
width of rectangular plot is 49m
