To find the perimeter, multiply the longest side of the rectangle by 4.
To find the area of the square, find the area both rectangles and add them together.

Step-by-step explanation:
I think your question is missed of key information, allow me to add in and hope it will fit the original one.
Please have a look at the attached photo.
My answer:
1. Chuck wants to draw three-dimensional figures whose lateral faces are rectangles. He says he can draw prisms and pyramids. Do you agree
No, I do not agree because:
- The lateral faces of a pyramid are triangles
- The lateral faces of a prism are rectangles
2. Part B. Chuck says that he can draw a cylinder on his polyhedron poster because it has a pair of bases that are congruent.
No, do not agree because:
A cylinder has two congruent bases but it is not a polyhedron while a cylinder has a curved surface when a polyheron has faces that are polygons
Hope it will find you well.
Answer:
2000.8 m or 2km height
(π 0.07^2)×2000 = 30.78 m^3.
Step-by-step explanation:
The total surface area of a cylinder of radius 7 cm is 880 m^2. Find the height and the volume of the cylinder.
"A cylinder is flat" according to curvature theory (unlike a sphere, where triangle angles can add to more than 180°). So unwrap it and compute area as circumference times height, or height as area divided by circumference. 880m^2 / (2 π 0.07 m) gives height = 2000.8 m or 2km (!!)
The volume of a cylinder is cross section area times height. (π 0.07^2)×2000m = 30.78 m^3.
M∠2 = 180 - m∠1 = 180 - 3x [supplementary angles<span>]
</span>In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180 <span>
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50</span>
SOH CAH TOA tells you the sine ratio is
Sin = Opposite/Hypotenuse
sin(x) = 12.5/15
Then the angle x can be found using the inverse function.
x = arcsin(12.5/15) ≈ 56°
The appropriate choice is
b) 56
