Mr. Jones rents an office in a building for $600 a month. His office has an area of 1,250 square feet. At the same rate, how much will it cost to rent an office with an area of 3,000 square feet?

$1440

Step-by-step explanation:

From the above question:

We know that the rate is

1250 ft² = $600

3000 ft² = x

Cross Multiply

1250ft² × x = 3000ft² × $600

x = 3000ft² × $600/1250ft²

x = $1440

Therefore, at the same rate, the cost of an office with an area of 3000 square feet is $1440

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
