Ascale model of a rectangular building lot measures 7 feet by 5 feet. if the actual house will be built using a scale factor of 12, what is the area of the actual building lot? 35 square feet 420 square feet 840 square feet 5,040 square feet

answer: 72: 111

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x^2 + y^2 = 1024

discussion:

the equation of a circle with center (h,k) and radius "r" is

(x-h)^2 + (y-k)^2 = r^2.

in our case

(x-0)^2 + (y-0) ^2 = 32^2 = 1024
