Find the surface area of the regular pyramid. Round to the nearest tenth if necessary

1008 square yards

Step-by-step explanation:

The surface area of the regular pyramid is the sum of the triangular faces and the square base.

The formula for determining the surface area of a triangle is expressed as

Area = 1/2 × base × height

Height = 19 yd

Base = 18 yd

Area of each triangular face

= 1/2 × 18 × 19 = 171 square yards

Area of the 4 triangular faces is

4 × 171 = 684 square yards

Area of the square base = 18² = 324 square yards

Therefore, area of the pyramid is

684 + 324 = 1008 square yards

answer: y=0 if that is what u r looking for

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
