The area of a pyramid is the sum of area of the base and the area of slant triangles.
The area of the base is 1.5 × 1.5 = 2.25 cm²
The slant height of each triangle, s is 3 cm
The area of the triangles = 1/2 × 1.5 × 3 × 4
= 9 cm²
Therefore, the area of the pyramid
=9 +2.25
= 11.25 cm²
First, simplify the given expression: combine 1 and 9 to get 10.
Then the problem reduces to 1/3 + 1/4 + 10.
The LCD of these two fractions is 12, and so, after conversion to LCD 12, we get
4+3
----- + 10 => 10 7/12, or 127/12
12
