Answer:
A. 96
Step-by-step explanation:
The surface area is the sum of the areas of the two triangular bases and the areas of the three rectangular lateral faces.
A = 2(1/2)bh + PH
where b is the base of the triangle, h is its height, P is the perimeter of the triangle, and H is the height of the prism.
A = (3 cm)(4 cm) +(3 +4 +5 cm)(7 cm) = 12 cm² +84 cm²
A = 96 cm²
The surface area of the triangular prism is 96 square cm.
The first is yes and the second is no
The property identity of multiplication is applied in the given statement.
<h3>
Properties of Multiplication</h3>
The properties of multiplication are:
- Distributive: a(b±c)= ab±ac
- Comutative: a . b = b. a
- Associative: a(b+c)= c(a+b)
- Identity: b.1=b
From the property identity, you know that the product between any number by the number 1 equals that number. Example: 3 • 1=3.
The question shows 10=10•1. Like, it was shown previously, this occurs due to the identity property of multiplication.
