Shelly sews a square blanket that has an area of 144 square ft. It has 36 square blocks each of the same size, what is the approximate length of each side of a block. A.1 foot B.2 feet C.3 feet D.4 feet
Find the area of 9ft 6ft
To find the length of the base of the triangle, we can use the formula for the area of a triangle:
Area = (base * height) / 2
In this case, we are given the area as 9 square feet and the height as 6 feet. Plugging these values into the formula, we get:
9 = (base * 6) / 2
To solve for the base, we can multiply both sides of the equation by 2:
2 * 9 = base * 6
18 = base * 6
Finally, we can divide both sides of the equation by 6 to solve for the base:
18 / 6 = base
Therefore, the length of the base of the triangle is 3 feet.
area of triangle = (1/2)(base)(height)
9 = (1/2)(base)(6)
multiply both sides by 2
18 = 6*base
divide both sides by 6
