Step-by-step explanation:
Area of board = 120×90
= 10800 sq cm
Area of paintings made by Himanshi and Maitreye = 2× (Area of each painting)
= 2× (60×30)
= 2× 1800
= 3600 sq cm
Area of painting that Tanya must make =
Area of board - Area of paintings made by Himanshi and Maitreye
= 10800 - 3600
= 7200 sq cm
