Mathematics
1 answer:
liraira [26]3 years ago
5 0

Answer:

A

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = \frac{1}{2} product of diagonals

Here AC = 13 and BD = 15 are the diagonals, hence

A = 0.5 × 13 × 15 = 97.5 units² → A

The rectangular prism shown has a surface area of 488 square inches. What is the length of the prism?
BigorU [14]

Answer:

length of the prism = 244 - (width x height) / width + height)

Step-by-step explanation:

Let length be a and width be b and height be c

2 (a * b) + 2 (b* c) + 2 (a * c) = 488

2ab+ 2bc + 2ac = 488

ab + bc + ac = 244

ab + ac = 244 - ac

a (b + c) = 244-ac

a = 244-bc / b + c

Therefore the length of the prism = 244 - (width x height) / width + height)

<em>Subtract 3 from both sides</em>

ax=3

<em>Put x in</em>

-3a=3

a= -1
