Answer:

D. A rectangle, 4 inches by 2 inches

Step-by-step explanation:

The length of the rectangular prism is 4 inches and the width is 2 inches and the height is 3 inches. On the red line that they give you to solve it does not give us the height. It only gives us the length and the width, which is already given to us in the rectangular prism.

Thus, the correct answer is D. A rectangle, 4 inches by 2 inches.

Joshua finds the perimeter of the following composite figure composed of a square and right triangle so that a braid may be cut

Bumek [7]

The perimeter of a shape is the sum of its side lengths.

<em>Joshua miscalculated the third length of the triangle</em>

First, we calculate the third length (x) of the triangle.

Because the triangle is right-angled, we can make use of Pythagoras.

So we have:

$x^2 = 7^2 + 7^2$

$x^2 = 2(7^2)$

Take square roots of both sides

$x = \sqrt{2(7^2)$

$x = 7\sqrt{2$

The other shape in the figure is a square.

So, the perimeter (P) is

$P = 7 + x + x + x + 7$ ---- i.e. the sum of the visible lengths

So, we have:

$P = 7 + 7\sqrt2 + 7\sqrt2 + 7\sqrt2+ 7$

Evaluate like terms:

$P = 14 + 21\sqrt2$

Hence, Joshua's error is that:

<em>He miscalculated the third length of the triangle</em>
