<h2>Answer:</h2>
The area of the figure is: 57 mm²
<h2>Step-by-step explanation:</h2>The area of figure is the sum of the area of rectangle (with dimensions 9 mm × 5 mm) and the second rectangle ( with dimensions 3 mm × 4 mm )
We know that the area of rectangle with dimensions a×b is ab square units.
Hence,
The area of rectangle with dimensions 9 mm×5 mm is: 45 mm²
and the area of rectangle with dimensions 3 mm×4 mm is: 12 mm²
Hence, the total area of figure is:
45+12= 57 mm²

*see attachment for the diagram of the triangular prism box
Answer:
528.8 in.²
Step-by-step explanation:
Surface area of triangular prism = 2(BA) + P*H
Area of triangular base (BA) = ½*b*h
b = 24.5 in.
h = 12 in.
BA = ½*24.5*12 = 147 in.²
Perimeter of triangular base = 24.5 + 17.1 + 17.1 = 58.7 in.
Height of prism = 4 in.
Plug in the values into the surface area formula:
Surface area of prism = 2(147) + 58.7*4
= 294 + 234.8
= 528.8 in.²
Answer:
(A)
(B)
Explanation:
(A) Slope: y = mx + b
m = 3/7
b = 2/7
Slope =
M =
Y intercept
Plug in
Isolate B
b =
(B) 4 = x, 2 = y
2 = 3/7 * 4 + 2/7
