Answer 1

57 sq units area is needed to be covered with flower Petals

Step-by-step explanation:

radius of Each circle = 5

shaded portion of the rangoli  = 8 arc segment  of 90° angles - area of 8 right angle isosceles triangle (with side = radius)

= 8 (  (90/360)π r²   -  (1/2)*r*r )

= 8 ( (1/4)(3.14) * 5² - (1/2) * 5² )

= 8 * 5² ( 0.785 - 0.5)

= 200 (0.285)

= 57 sq units
