This figure is what we would call a composite figure. A composite figure is a shape that is made up of multiple other shapes. when looking at the pond and the border that surrounds it, we can see that this heart shape is made up of two semi circles and a square. To find the area of the border, we will use the area formulas for semi circles and for squares:
Semi Circle Area Formula:
÷ 2
Square Area Formula: length x width
Pi = 3.14
Radius = Half of the diameter, in this case 6
After finding the area of each shape, we can subtract the 2 ft width to find the area of the flower bed border.

Step-by-step explanation:
Formula for z:
, where x= data value corresponding to z,
= mean,
= standrad deviation.
Given: =85.3,
=4.85, z=0.55
To find : x
Hence, The required data value= 87.9675
