Given the net with dimensions below, find the surface area of the shape.
Colt1911 [192]

Answer:

136 cm²

Step-by-step explanation:

I'm going to split the net into:

2x          7 cm by 2 cm rectangles

2x          6 cm by 7 cm rectangles

2x          6 cm by 2 cm rectangles

The 2x means there's 2 of them.

Let's find the area of the 2x 7 cm by 2 cm rectangles:

2*7*2=

4*7=

28 cm²

Let's find the area of the 2x 6 cm by 7 cm rectangles:

2*6*7=

2*42=

84 cm²

Let's find the area of the 2x 6 cm by 2 cm rectangles:

2*6*2=

12*2=

24 cm²

Adding all these areas together gives us the surface area of the net:

28+84+24=136 cm²

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b
Goshia [24]

Given steps  :

Step 1: m∠m + m∠n + m∠o = 180 degrees (sum of angles of a triangle)

Step 2: m∠p − m∠o = 90 degrees (alternate interior angles) : <em>It's incorrect step because m<p and m<0 are on a common point on a line and make a linear pair. Therefore, m<p and m<0 are supplementary angles.</em>

Step 3: Therefore, m∠m + m∠n + m∠o = m∠o + m∠p.

Step 4: So, m∠m + m∠n = m∠p.

<h3>Therefore, student did mistake in 2nd step and correct step should be  Step 2; it should be m∠o + m∠p = 180 degrees (supplementary angles).</h3>
