hey friend here is your answer
Side of square = 132/4 = 33 cm.
Area of square = 33 x 33 = 1089 cm2
Side of equilateral triangle = 132/3 = 44 cm.
Area of equilateral triangle
= (root3/4 ×44×44)cm²
= 484×root3 cm²
= 484×1.73 cm² = 822.8 cm²
Circumference of circle = 132
=> 2 × 22/7 × r = 132
=> r = 21 cm
∴ Area of circle
= 22/7 × 21² = 1386 cm²_____answer
hope it will help..
