Question

The measurement of a window is 2.4 m $\times$1.8 m, if 6 doors are to be fixed in that window in two rows, measurements of each door should be

• A. 80 cm $\times$ 90 cm
• B. 60 cm $\times$ 60 cm
• C. 24 cm $\times$ 18 cm
• D. 240 cm $\times$ 180 cm

Answer 1

The correct option is A 80 cm $\times$ 90 cm

Area of window=$2.4\times 1.8=4.32m^2$

Since we have tofit in two rows

$2\times$length of door=length of window

$2\times l=1.8⟹l=0.9m$

Also similarly

$3\times b=2.4\times b=0.8m$

Hence dimmension of door is $90cm\times 80cm$.
