a)

A = 10x5 = 50 cm²

b)

c)

A = B = 4x5/2 = 20/2 = 10 cm²

d)

A = 50cm² - 2x10cm² = 50cm² - 20cm² = 30 cm²

a) 10*5 = 50cm²

b)½×4×5= 10 cm²

c) same as triangle A i.e, 10 cm²

d)6*5 = 30 cm²

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
