Answer:
A square with an area of 49 square inches has a perimeter of 28 inches.
Step-by-step explanation:
The square root of 49, or 7 inches, is then the length of one side. The formula for the perimeter of a square is the sum of all sides. Since all sides are 7 inches, the perimeter is 7 + 7 + 7 + 7, or 28 inches. The area of the square is reported in square inches because inches are multiplied by inches to yield square inches.
This is problem of ratio and proportion. to solve this, fisrt is calculate the convertion factor.
so the house is 30 feet in actual and 4 in wide on drawing
30 feet / 4 in = 7.5 feet / inso in every inch in the drawing is equivalent to 7.5 feet on actual.
1.2 in ( 7.5 ft/ in) = 9 ft
1.6 in ( 7.5 ft/ in) = 12 ft
(4x² + 2y)(3x + y²<span>) =
12x</span>³ + 4x²y² + 6xy + 2y³
<span>The coefficient of xy is 6</span>
