The diagram shows a cube of side length 4 inches. A is a vertex of the cube, while B and C are located on opposite edges of the
cube with both B and C being 1 inch from the nearest vertex.
If a plane including the points A, B, and C cuts through the cube, what is the shape of the resulting cross section?
an isosceles triangle
a rectangle
a square
a rhombus
a hexagon

Answer:
530 m²
Step-by-step explanation:
First of all we need to label the missing sides ,please check the figure I provided for that :
x = 37 - (10+ 15) = 37 - 25 = 12
z = 10
y = 2 × 10 = 20
The shade does area = area of the whole rectangle − the white area
= 37 × 20 − [ (15×20)÷2 + (10×12)÷2 ]
= 740 − [ 150 + 60 ]
= 740. − 210
= 530
