Question
An office building has a room with a square-shaped floor. The actual length of the floor is 90 times the length of the floor on a blueprint drawn to scale. The actual area of the floor is p times the area of the floor on the blueprint. What is the value of p ?
The correct answer is: 8100
Explanation :
Step 1:
let a1 be the side or length of square on site and a2 be the length of square on blue print. Given, = 90
Step 2: Then area’s of respective squares will be (a1)2 and (a2)2
Then the ratio of the areas of squares are []2 = p
So p= ()2
P = (90)2
∴The value of p is 8100
