What is the area in square units ?

What is the equation?

84 square units

Equation: (8 x 3) + (5 x 12) = 84

Step-by-step explanation:

First, we split one rectangle from the other. We will split the part where it says 8 x 3.

8 x 3 = 24

(24 is the first rectangle.)

Next we have the larger rectangle at the bottom.

We do 8 - 3 first because we cut off the top part.

8 - 3 = 5

Now we know the bottom rectangle measures: 5 x 12

5 x 12 = 60

Now we add both of the squares areas together:

24 + 60 = 84

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
