Answer:
5) 162
6) 61.6
Step-by-step explanation:
Area of triangle = [tex]\frac{1}{2} b*h[/tex]
Area of rectangle = w * l
5)
Left triangle Area = [tex]\frac{1}{2} 4*3[/tex]
= 2*3
=6
Right triangle Area = [tex]\frac{1}{2} 7*8[/tex]
=[tex]\frac{56}{2}[/tex]
=28
Rectangle Area = 16*8 = 128
Total Area = 128+28+6 = 162
6)
12-10 = 2
base of each traingle is 2/2 = 1
Left triangle = right triangle = [tex]\frac{1}{2} 5.6*1[/tex] = 2.8
Rectangle = 10*5.6 = 56
Total = 2.8+2.8+56 = 61.6
