Amount of paper need = 47.88 in²

Step-by-step explanation:

Given:

Square base side = 4.2 in

Height of triangle = 3.6 in

Find:

Amount of paper need

Computation:

Amount of paper need = Area of square base + 4[Area of triangle]

Amount of paper need = Side² + 4[1/2][b][h]

Amount of paper need = 4.2² + 2[4.2][3.6]

Amount of paper need = 17.64 + 30.24

Amount of paper need = 47.88 in²
