Question

There is a grassbed of width 1.5 m along the
four sides of a square pond of side 27 m. Find
the area of the grassbed.​

Answer 1

Answer:

 171 sq m

Step-by-step explanation:

Area of grass bed = area of large square - area of small square

area of large square = 27+ 1.5 + 1.5 = 30 (1.5 on either sides of the square

                                   = 30^2

                                   = 900

Area of small square = 27^2

                                   = 729

900 - 729 = 171

               171 sq m is the area of the grass bed

Answer 2

Given :  There is a grassbed of width 1.5 m along the 4 sides of a square pond of side 27 m.

To Find :  the area of the grassbed.

​

Solution:

square pond of side 27 m.

Area of square pond = 27²

grassbed of width 1.5 m

Hence  total side length   = 27 + 1.5 + 1.5  = 30 m

Area including grassbed = 30²

area of the grassbed. = 30² - 27²

= (30 + 27)(30 - 27)

= 57(3)

= 171  m²
