A rectangle has a height of 4 and a width of x2 + 3x + 2.

Question:

A rectangle has a height of 4 and a width of x² + 3x + 2. Express the area of the entire rectangle.

Given:

The height of the rectangle is 4.

The width of the rectangle is

We need to determine the area of the entire rectangle.

Area of the entire rectangle:

Let us determine the area of the entire rectangle.

The area of the rectangle can be determined using the formula,

Substituting height = 4 and width =

Thus, we get;

Multiplying the terms by 4, we get;

Thus, the area of the entire rectangle is

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
