What is the surface area of the composite figure
shown?
107 square feet
O 172 square feet
O 279 square feet
O 321 square feet

Faces:
Triangles (2): A = 1/2(5)(7)
Rectangles: 2 are 6 by 6; 2 are 5 by 6; 2 are 7 by 5; 1 is
6 by 7

answer is because 4×10=40

and 98×4= is 392

40,392

answer: im sorry i dont get it

step-by-step explanation:

the answer is:

the lateral area is equal to

to find the lateral area of the square pyramid, first we need to find the perimeter of the base, and then, find the lateral area using the following formulas:

where,

s, is the base length

slant height, is the height of a the side of the pyramid

we are given:

now, calculating the perimeter of the base, we have:

then, calculating the lateral area:

hence, we have that the lateral area is equal to
