Step-by-step explanation:the 3.4 doesn't need to be added just 5.7 times four because all the sides are equal

for number 4: the area is 19.38 sq cm

for number 6: the area is 57.4 sq mm

Step-by-step explanation:

for number 4:

start with the formula:

A = bh

Then substitute b for 5.7 cm and h for 3.4 cm.

A = 5.7 cm times 3.4 cm

This equals 19.38 sq cm.

for number 6:

start with the formula:

A = 1/2 bh

Substitute b for 14 mm and h for 8.2 mm.

A = 1/2 times 14 mm times 8.2 mm

This equals 57.4 sq mm.

y = x + 95

y = 42 + 95

y=137 mm hg
