Answer:
84 cm squared, 30 cm squared, 18 cm squared
Step-by-step explanation:
Formula for triangle area= 1/2 Base * Height
Area for triangle ABD= 1/2 (12cm)*(14cm)
=84 cm squared
Area for triangle BC(orange triangle)= 1/2 (6cm)*(10cm)
=30 cm squared
BC= half of BD
Area for triangle CD(Green triangle)= 1/2 (6cm)*(4cm)
=12 cm squared
Answer:
option A is correct.
Explanation:
Total Area of the prism: 8 + 48 + 8 + 24 + 24 + 48 = 160 ft²
<u>Area of rectangular prism</u>: 2(LW+HW+HL)
<u>Option A</u>
2(2*4+4*12+12*2)
2(8+48+24)
2(80)
160 ft²
2.15 + 2.5 = 2.65
2.65 + 3.85 = 6.40
If it is 0.5
6.40 + 0.5 = 0.9
If you meant 0.05
6.40 + 0.05 = 6.45
If you meant 5 (as in the whole number)
6.40 + 5 = 11.40
