Answer 1

area of shaded region= 162 square centimetre

Answer 2

Answer:

145.5 cm²

Step-by-step explanation:

area of two triangles = 2*1/2*4*5 cm²

= 4*5 cm²

= 20 cm²

area of the circle = π*(3.5)² cm²

= 22/7*3.5*3.5 cm²

= 22*0.5*3.5 cm²

= 38.5 cm²

area of the rectangle = 17*12 cm²

= 204

total area of triangles and circle = (20+38.5) cm²

= 58.5 cm²

area of the shaded region = (204-58.5) cm²

= 145.5 cm²

using formula

area of a triangle = 1/2*height*base

area of a circle = π*(radius)²

area of a rectangle = length*width
