Answer:
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:
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.
