Answer:
2d or 2 dimensional is the answer i think
Step-by-step explanation:
since area is measured for 2d shapes and surface area is just finding the area of each side separately and adding it together
Answer:
Step-by-step explanation:
Measure of second angle = 90° - x°
9514 1404 393
Answer:
144 square meters
Step-by-step explanation:
The formula for surface area of a cuboid is useful.
A = 2(LW +H(L+W))
A = 2((6 m)(6 m) +(3 m)(6 m +6 m)) = 2(36 m² +36 m²)
A = 144 m²
The surface area of the figure is 144 square meters.
Answer:
12
Step-by-step explanation:
a^2 + b^2 = c^2
(16)^2 + b^2 = (20) ^2
b^2 = 400 - 256
b = = 12
I hope im right!!
Answer:
sqrt 144
Step-by-step explanation:
formula for area of a square us s^2,
s^2 = 144
square root both sides
