the lawn​

Answer 1

Answer:

The area of the lawn is 2711.6 $m^{2}$

Step-by-step explanation:

From the above question,

They have given :

A lawn is rectangular in the middle and it has semicircular portions along the shorter sides of the rectangle. The rectangular portion measures 50m by 35m.

Here we need to find the area of the lawn​,

Let us consider there are semicircular portions along the shorter side then the diameter will be 35m and radius 35/2m i.e., 17.5 m.

Area of lawn = Area of rectangle + Area of 2 semicircular portions

To find the area of a parallelogram having base 'b' and height 'h.

           Area = l * b +  2 * pie * r2 / 2

                     = 50 * 35 + 3.14 * 17.52

                     = 2711.625 $m^{2}$

so, the area of the lawn is 2711.6 $m^{2}$
