A architect is designing a house. The scale on the plan is 1 inch=6 feet. If the house is to have a length of 90 feet and a width of 30 feet, how long will the line representing the house's length on the blue print

90/6 = 15 inches

A dollhouse is 6 feet long an 4 feet wide wht is tha area of tha dollhouse

it would be 15inches

To determine the length of the line representing the house's length on the blueprint, we need to use the given scale of 1 inch = 6 feet.

First, find the length of the house in inches by dividing the actual length of the house (90 feet) by the conversion factor (6 feet/inch):

Length in inches = 90 feet / 6 feet/inch
Length in inches = 15 inches

Therefore, the length of the line representing the house's length on the blueprint would be 15 inches.
