surface area = area of 4 triangles + area of square

OpenStudy (faiqraees):

the triangular area can be calculated by 1/2 * b * h and square will be l*l

OpenStudy (igreen):

\(\sf SA = \dfrac{1}{2}pl + B\)

OpenStudy (igreen):

Where 'p' is the perimeter of the base, 'l' is the slant height, and B is the area of the base.

OpenStudy (igreen):

The length of one side of the base is 5. To find the perimeter, multiply it by 4. To find the area, square it. Can you find the perimeter and area of the base?

1/2*16*7+25

OpenStudy (igreen):

Not quite..the perimeter of the base isn't 16.

OpenStudy (shaleiah):

Sorry, the perimeter would be 20..

OpenStudy (shaleiah):

5*4

OpenStudy (igreen):

Yes..so re-do the calculations
