Answer:

Option C is correct.

Step-by-step explanation:

Given:

Length of the base rectangle = 15 unit

Width of the  base rectangle = 15 unit

Height of triangle on the side of pyramid = 15 unit

Length of the base of the triangle = 15 unit

Surface are of the rectangular pyramid = Area of Base + 4 × Area of triangle on side.

Area of base = length × width = 15 × 15 = 225 unit²

Area of the triangle = 1/2 × base  × height = 1/2 × 15 × 15 = 112.5 unit²

Surface Area = 225 + 4 × 112.5  = 225 + 450 = 675 unit²

Therefore, Option C is correct.

I'm assuming you only need the first triangle. You didn't specify. If you need it after I answer the first one I'll be happy to help though.

To find the area of a triangle you go b(h)/2=a

6cm(3cm)/2
18/2
Area=9

To find the perimeter you add all of the sides together.

4+4+6=P
4+10=P
14= Perimeter

Solve the equation −2w+4=−12. URGENT Solution
VMariaS [17]

Answer:

The solution is w=8

Step-by-step explanation:

we have

-2w+4=-12

Solve for w

That means -----> isolate the variable w

Subtract 4 both sides

-2w+4-4=-12-4

-2w=-16

Divide by -2 both sides

-2w/-2=-16/-2

w=8

1 1/5 + 3/4 - (-3 3/5) - (-2 1/4)
babymother [125]

Step-by-step explanation:

= 1 \frac{1}{5}  +  \frac{3}{4}  - ( - 3 \frac{3}{5} ) - ( - 2 \frac{1}{4} )

= 1 \frac{1}{5}  +  \frac{3}{4}  + 3 \frac{3}{5}  + 2 \frac{1}{4}

= (1 + 3 + 2) + ( \frac{1}{5} +  \frac{3}{4} +  \frac{3}{5}   +  \frac{1}{4}  )

= 6 + ( \frac{4 + 15 + 12 + 5}{20} )

=  6 +  \frac{36}{20}

= 1 + 6 +  \frac{16}{20}

= 7 +   \frac{4}{5}

= 7 \frac{4}{5}
