Question

A rectangle that is 11.2 inches by 8 inches. The scale in the plan is 4in:5ft find the length and width or the actual studio. Find the area of the actual studio

Answer 1

`l=14\,ft\,\,\,\,w=10\,ft\\\\Area\,\,of\,\,actual\,\,studio=140\,ft^2\\\\`

Explanation:

As we know 1 ft has 12 inches.

`scale\,\,in\,\,the\,\,plan=(5\,ft)/(4\, in)\\`

We can find the length and width of studio by multiplying rectangle parameters with scale.

`l=11.2\,in* (5\,ft)/(4\,in)\\\\l=14\,ft\\\\w=8\,in * (5\,ft)/(4\,in)\\ \\w=10 \,ft\\\\Area\,\,of\,\,actual\,\,studio=14* 10=140\,ft^2\\`
