Step-by-step explanation:
A: area of the triangle = ![\frac{1}{2}bh = \frac{1}{2}(10)(4) = \frac{1}{2}(40) = 20 ft^{2} \\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dbh%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2810%29%284%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2840%29%20%3D%2020%20%20ft%5E%7B2%7D%20%5C%5C)
B: area of the rectangle + area of the triangle =![(5*6) + \frac{1}{2}(5)(6) = 30+15=45 ft^{2}](https://tex.z-dn.net/?f=%285%2A6%29%20%2B%20%5Cfrac%7B1%7D%7B2%7D%285%29%286%29%20%3D%2030%2B15%3D45%20ft%5E%7B2%7D)
C: area of the rectangle + area of the trapezoid = ![(6*2) + \frac{1}{2}(b_{1} +b_{2})(h) = (6*2)+ \frac{1}{2}(2+5)(5) = 12+\frac{1}{2}(35) = 29.5 ft^2](https://tex.z-dn.net/?f=%286%2A2%29%20%2B%20%5Cfrac%7B1%7D%7B2%7D%28b_%7B1%7D%20%2Bb_%7B2%7D%29%28h%29%20%3D%20%286%2A2%29%2B%20%5Cfrac%7B1%7D%7B2%7D%282%2B5%29%285%29%20%3D%2012%2B%5Cfrac%7B1%7D%7B2%7D%2835%29%20%3D%2029.5%20ft%5E2)
E: area of the triangle = ![\frac{1}{2}bh = \frac{1}{2}(14)(4) = \frac{1}{2}(56) = 28 ft^{2} \\](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7Dbh%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2814%29%284%29%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2856%29%20%3D%2028%20%20ft%5E%7B2%7D%20%5C%5C)
