Question

Find the area of the shaded part. Equal number of tick marks are placed to indicate equal measures of parts of the figures

Answer 1

1) 36 cm²

2) 109.938 in²

Explanation:

1) Area = Big Rectangle - Smaller Rectangle

= (10)(9) - (6)(9)

= 90 - 54

= 36 cm²

2) Area = Circle - Rectangle

= πr² - bh

= (π)(7)² - (11)(4)

= 49π - 44

approximately equal to 109.938 in²
