Please help! I need help with a clear explanation..

138920m^2

Step-by-step explanation:

Like you can see from the picture, piramide has square for base, and 4 triangle.

Surface is sum of those element.

S=B+4T, B is surface for Base and T is survace are for triangle, and all 4 triangle are the same, because we use 4T.

B is square so,

B=a*a=230*230=52900m^2

T=a*h/2=230*187/2=21505m^2

S=52900+4*21505=52900+86020=138920m^2

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

choice b is correct
