Find the surface are of the pyramid

Step-by-step explanation:

SA=1/2(Perimeter of Base)(slant height) + Area of Base

SA=1/2(14X4)(25) + (14X14)

SA=1/2(56)(25) + (196)

SA=1/2(1,400) + 196

SA=700+196

SA=896 square meters

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

show us the triangle so we can answer it
