How many square feet of grass are there on a trapezoidal field with a height of 75 feet and bases of 125 feet and 81 feet.
I know the formula is A = h( b + b) / 2
A = 75 ( 125 + 81) / 2
A = 75 ( 206 ) /2
it doesn't matter. Either way, answer will be same.
Your work so far is correct.
OK, my question is do you divide the 206 and multiply times 75 or multiply 75 times 206 and then divide by 2
Thanks! y’all are correct so far :)
Divide 206 by 2. Your re-written expression should look something like this: 75[(125+81)/2] you use brackets since we want to work with everything inside and THEN multiply it by 75.
To solve for the area of the trapezoidal field, we can use the formula A = h(b1 + b2)/2, where A represents the area, h represents the height, and b1 and b2 represent the lengths of the bases.
In this case, the height is given as 75 feet, and the bases are 125 feet and 81 feet. Plugging these values into the formula, we get:
A = 75 (125 + 81) / 2
Now, we need to perform the arithmetic calculations inside the parentheses:
A = 75 (206) / 2
Next, we multiply 75 by 206:
A = 15,450 / 2
Finally, we divide 15,450 by 2 to get the final result:
A = 7,725
So, the trapezoidal field has an area of 7,725 square feet.
