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

Answer:

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

Step-by-step explanation:

As we know 1 ft has 12 inches.

$scale\,\,in\,\,the\,\,plan=\frac{5\,ft}{4\, in}$

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

$l=11.2\,in\times \frac{5\,ft}{4\,in}\\\\l=14\,ft\\\\w=8\,in \times \frac{5\,ft}{4\,in}\\ \\w=10 \,ft\\\\Area\,\,of\,\,actual\,\,studio=14\times 10=140\,ft^2$
