SOLUTION
GIVEN
Jai’s garage is 3 m wide and 8 m long.
TO DETERMINE
The dimensions of this garage on a plan with a scale of 1 : 200
Length _______ cm
Width ________ cm
EVALUATION
Here it is given that Jai’s garage is 3 m wide and 8 m long.
Now 3 m = 3 × 100 cm = 300 cm
8 m = 8 × 100 cm = 800 cm
Now it is given that the dimensions of this garage on a plan with a scale of 1 : 200
We know that if the scale is 1 : 200, the real life measurements will be 200 times larger.
In real life Jai’s garage is 300 cm wide and 800 cm long.
Hence on a plan with a scale of 1 : 200
Length = 800 ÷ 200 cm = 4 cm
Width = 300 ÷ 200 = 1.5 cm
FINAL ANSWER
On a plan with a scale of 1 : 200
Length = 4 cm
Width = 1.5 cm
