Answer:
Area = 28 cm² (check the attached diagram for better clarity)
Step-by-step explanation:
The question is incomplete but let's see a similar example
The front of a rectangular pyramid can refer to either one of two possibilities: it could be either the side that has the breadth and the height or the side that has the length and the height. In this case, we were given the formula for calculating the area of the front face of this rectangular prism as the product of breadth and height
Mathematically,
A = bh
From the attached diagram, we will see the properties of the rectangular prism as:
length = 5 cm, breadth = 4 cm, height = 7 cm
To calculate for the front face, we use A = bh,
⇒ A = 4 * 7 = 28 cm²
Example 2
If the breadth of the rectangular prism is 2 cm and the height is 3 cm, we have:
A = 2 * 3 = 6 cm²
Step-by-step explanation:
See the attached image. I numbered angles differently so as not to make an <u>assumption</u> that angles numbered the same are congruent.
(alternate interior angles are congruent)
(alternate interior angles are congruent)
(opposite sides of a parallelogram are congruent)
(ASA - side/angle/side)
(corresponding parts of congruent triangles are congruent)
The diagonals bisect each other!
