Ответ:
552 in^2
Step-by-step explanation:
Area of trapezoid = 1/2(16 + 30(12)
= 1/2(46)(12)
= 276
Two trapezoids are similar
So total area = 2 x 276 = 552 in^2
Ответ:
The area of a trapeziod is found by adding the top and bottom dimensions together, dividing that by 2, then multiplying by the height.
The top half of the window is: 16 +30 = 46/2 = 23 x 276 square inches.
The top and bottom are the same.
Total area = 276 + 276 = 552 in^2
