Question

the shape of a garden is rectangular in the middle and semi circular at the ends . find the area and the perimeter of this garden [Length of rectangle is
$20 - (3.5 + 3.5)$
metres].

Answer 1

Answer:

20 m = Total length.

7 m = Diameter.

7 / 2 = 3.5 m = Radius.

= 20 - ( 3.5 + 3.5 ) = 20 - 7 = 13 m

= 7 m = Breadth.

Length × Breadth = area of rectangular field.

= 13 × 7 = 91 cm²
