Surface area is just the area of all these 4 triangles plus the rectangle.

First we can find the area of the rectangle.

$\sf A=lw$

Half of the length is 28 cm, so the full length must be 28 * 2 = 56 cm.

$\sf A=(56)(27)$

$\sf A=1512cm^2$

The base for the left and right triangles are 27. The heights would be the net length minus half the length of the rectangle:

$\sf 82.8-28=54.8\? cm$

Calculate the area:

$\sf A=\dfrac{1}{2}bh$

$\sf A=\dfrac{1}{2}(27)(54.8)$

$\sf A=739.8\?cm^2$

We have two of these triangles.

$\sf 739.8\times 2=1479.6\? cm^2$

Now do the other two pair of triangles. The bases for them are 28 + 28 = 56 cm. The heights would be the net width minus the width of the rectangle:

$\sf 81.2-27=54.2\?cm$

Now find the area:

$\sf A=\dfrac{1}{2}bh$

$\sf A=\dfrac{1}{2}(56)(54.2)$

$\sf A=1517.6\? cm^2$

We have two of these triangles.

$\sf 1517.6\times 2=3035.2\?cm^2$

Add all the areas together:

$\sf 1512+1479.6+3035.2=\boxed{\sf 6026.80\? cm^2}$

Katelyn can complete 17 integer questions in one minute. Collin can also complete 17 integer questions in one minute. Which expr

BabaBlast [244]

Answer:

a: 17m + m

Step-by-step explanation:

Each one can answer 17 questions in 1 minute.

Each one can answer 17m questions in m minutes.

The total they can answer is 17m + 17m = 34m.

Every expression that is equal to 34m represents the amount they can both answer in the same number of minutes.

The expression we are looking for does not equal 34m.

a: 17m + m = 18m

b: 34m = 34m

c: 2(17m) = 34m

d: 17m + 17m = 34m

Only choice a does not equal 34m.

Answer: a: 17m + m
