Answer:
1. 45 in²
2. 108 cm²
3. 104 m²
4. 75 in²
5. 1140 ft²
6. 166.5 mm²
Step-by-step explanation:
b=base, h=height
1. Area of triangle = [tex]\frac{1}{2}[/tex] x bh
[tex]\frac{1}{2}[/tex] x 10(9) = 45
2. [tex]\frac{1}{2}[/tex] x 12(18) = 108
3. [tex]\frac{1}{2}[/tex] x 16(13) = 104
4. Area of a trapezoid: [tex]\frac{1}{2}[/tex] x h( length of base 1 +length of base 2)
[tex]\frac{1}{2}[/tex] x 6(10+15) = 75
5. Area of kite = [tex]\frac{1}{2}[/tex] x length of diagonal 1 x length of diagonal 2
diagonal 1 = 5*9 = 45
diagonal 2 = 8*8 = 64
[tex]\frac{1}{2}[/tex] x 45(64) = 1140
6. [tex]\frac{1}{2}[/tex] x 9 (13+24) = 166.5
