Me plz a toy pyramid has the dimensions shown below. the base of the pyramid is an equilateral triangle. what is the surface area of this pyramid? 7cm 6cm and 9cm 48 cm2 129 cm2 102 cm2 81 cm2

The base of the pyramid is the triangle on the very bottom. The formula for the area of a triangle is A = 1/2 x base x height.

In this triangle, the base length is 6 cm and the height is 7 cm, as shown clearly in the image. Using the formula for the area, we can easily solve for the area of this triangle.

A = 1/2 x 6 x 7

A = 1/2 x 42

A = 21 cm^2

Hope this helps! :)
