Question

a window has a hight of 1m and a width of 0.5 m two beams width 10cm each cross the window one parallel to the width and other parallel to the height find area of open part

Answer 1

Height of window : 1 m
Width of window : 0.5 m
Area of window : 0.5 * 1
= 0.5 m²

Width of Beams = 1/10 m
Height of beams = 1 m
Number of beams = 2
Area of beams = 1/10 * 1 * 2
= 1/5 m²
= 0.2 m²

Area of open part = 0.5-0.2
= 0.3 m²
