Question

The length and breadth of rectangular park are 14cm and 7cm respectively Two semicircular ponds are made inside the park by making the breadth as diameter and a flower garden is made in the remaining portion find the area of flower garden​

Answer 1

answer is 59.5

Step-by-step explanation:

area of garden = area of rectangle - area of 2 semicircles

= 98 - 2(πr^2/2)

= 98 - 38.5

= 59.5

Answer 2

Area of flower garden is 59.535 square centimeter

Solution:

Given that,

The length and breadth of rectangular park are 14cm and 7cm respectively

The area of rectangle is given as:

$Area\ of\ rectangle = length \times breadth\\\\Area\ of\ rectangle = 14 \times 7 \\\\Area\ of\ rectangle = 98\ cm^2$

Two semicircular ponds are made inside the park by making the breadth as diameter

Diameter = breadth = 7 cm

$Radius = \frac{7}{2} = 3.5\ cm$

Area of semicircle is given as:

$Area\ of\ semicircle = \frac{ \pi r^2}{2}$

Then area of two semicircular ponds is given as:

$Area\ of\ two\ semicircular\ pond = 2(\frac{ \pi r^2}{2})\\\\Area\ of\ two\ semicircular\ pond = \pi r^2 = 3.14 \times 3.5^2\\\\Area\ of\ two\ semicircular\ pond = 38.465\ cm^2$

A flower garden is made in the remaining portion

Find the area of flower garden​

Area of flower garden = area of rectangular park - area of two semicircular ponds

Area of flower garden = 98 - 38.465 = 59.535

Thus area of flower garden is 59.535 square centimeter
