Answer:
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
